GPS does not work after installing 2.0.1

[sowlerrmgh]

I installed the 2.0.1 update this morning and ever since the gps has not been working on google maps. The tower triangulation does not work either. I have tried restoring my iphone but it has not fixed it.

Does anyone else have any advice or is anyone suffering from the same problem? It is very annoying because i used the GPS feature most.

[manchoi44]

Same here... I am in Chicago

[imapfsr]

Same here in Victoria, Canada.

mine doesn't work either

i did and update...did anyone restore from scratch?

[seedster2]

same here in NYC.

mine just keeps searching....:mad:

[hkftw]

That's pretty weird. My GPS works fine, even after I updated to 2.0.1

I'm in San Francisco, California

[cambridge1807]

I think mine still works. Although it took a longer time to get the blue dot on my current location.

I'm in Orange County, CA

[philgilder]

mine's still working here (50 miles north of london)
although it was slightly inaccurate, but i was inside

[Penguinwrangler]

Same here, Northern Jersey. Just keeps searching.

[Mad Mac Maniac]

Works for me! Dallas, TX!

[Rigby]

For me, the location service is spotty when I'm on UMTS, but works perfectly when I'm on Edge. :confused: Perhaps the Skyhook database is incomplete for 3G towers? Or assisted GPS for some reason doesn't work well with UMTS?

Anyway, I think there must also be a software problem. Even if the cell tower positioning via Skyhook doesn't work, you should still get a GPS lock after a while. But in some cases the busy-indicator just keeps spinning and you never get a lock.

[sowlerrmgh]

I have now managed to get mine working by turning off location services in the settings menu and then turning them back on again.

[ssierra]

Mine works indoors, only if am connected to wifi, or ouside. My blackberry detects the position instantaneously although it hasn’t got GPS

I am in UK.

This is clearly a software issue.

[jfreak623]

Im in Louisville, KY and my GPS is also no longer working after new update

[jephersun]

That's pretty weird. My GPS works fine, even after I updated to 2.0.1

I'm in San Francisco, California

Ditto...im from San Francisco...n the GPS works the same...locates me in about 3-5 seconds...

[enklined]

Working perfect on EDGE and 3G here.

Sacramento, Ca.

[lavrishevo]

The GPS signal is fine. Don't forget how much being inside, cloud cover, weather can effect signal reception.

[Greggio]

Hmmm...I thought something might be wrong with mine. I got it new yesterday and it triangulated my position in the flat last night (although I suspect not by GPS).

Had patchy coverage all day because 02 was porting my number across and then it won't work at all this evening. Cell coverage has been fine, both Edge and 3G, Google Maps works, but the location thing - nothing!

[gloss]

Try turning off 3G and then getting a fix.

[spamdumpster]

12 miles north of Boston -- GPS works fine regardless whether on edge, 3g, and wifi.

[dobosh12]

Hello all,

I too have had an issue with location services since I upgraded to v. 2.0.1 last night. When i try to use location services in Maps and have 3G (with full bars), It just continuously searches but never find me. When i turned off the 3g and used maps, it found me within 5 secs.

Hope they figure out how to fix. None of the apps I have, including the Camera ask me to use it anymore since it cannot find me. :mad:

[pj rage]

That's so weird that alot of you are having problems. I'm pretty sure they changed something though, because mine is significantly BETTER after the update. I never had any real problems before, but after the update, the gps is locking on AT LEAST twice as fast as before (like 5-8 seconds now instead of 15-20 seconds). It also seems to be more accurate and tracks my position a bit smoother.

[stevearm]

Doesn't work.

London

[Cynicalone]

Still works on 2.0.1

<-Located right where it say's I am. Kinda creepy that I can watch the dot move with me as I move around my Condo. That's almost too accurate. :D

[Airij23]

A friend mentioned this problem to me this morning...I when i tried to locate the icon would just spin and not find me...tried with 3g off/wireless off etc. All i did was power off my iPhone and power it back on...everything worked good as new after that and found my location right away.

I suggest just powering off and back on and hopefully you will be fixed too

[t0mat0]

Used to get a lock inside on 2nd floor, near windows, but now taking much longer to get a lock, in car or in house. Also, when a lock is possible, hitting the GPS locate me button takes much longer. I'm resorting to putting as many wifi MAC addresses into Skyhook as I can :D

[FearlessFreep]

My GPS has been very good since the upgrade. Seems to update position more frequently.

[lavrishevo]

Another quick note. When I got off the plane in Puerto Rico last night it took it about five min. to find me so give it some time it your still having problems.

[dobosh12]

Hey All,

After posting yesterday, I stepped outside and my 3G picked up my location. It seems odd that inside my building w/ full 3G bars, it couldn't find me, but on EDGE inside the building it did. Once I stepped outside, both found me.

Does anybody know why this would happen? It can't be that the building is blocking the signal since I get all my bars for both and EDGE finds me no problem.

[Greggio]

I was having problems with mine in London and have found that it will only work if Wifi is turned on. I'd been turning it off when I left the house so it didn't ask me if I wanted to join a network. With it back on, the location thing seems to work pretty well.

[nickspohn]

I must be lucky because my GPS has actually been faster...

But who knows, it is 3AM in the morning. :rolleyes:

[sowlerrmgh]

mine is not working again!! It seems to be very temperamental. I am also in London so it could just be a geographical location problem...however i am connected to a wifi network and it still does not work

[Pilki]

Another quick note. When I got off the plane in Puerto Rico last night it took it about five min. to find me so give it some time it your still having problems.

Yeah, that's most likely because the GPS software would keep in its memory a vague idea of the last time you used it. Dedicated GPS units like TomToms and Garmins use this to give a location faster, so if you've moved quite a considerable distance since last you used it, then it's bound to take a wee while to get its bearings, almost as if you had turned it on for the first time.


For everyone else who's having problems, try pressing 'locate me' when you're outside. GPS units have a hard time getting a signal indoors so you're not doing it any favours trying to get a location inside.

Hope this helps! :)

[woodekm]

GPS works outdoors but when indoors and in 3G mode, it doesn't. Just searches and BURNS battery.

I guess its ok for now, but want a fix.


Other than that, for me, it is actually perfect, especially after the 2.0.1 update.

Just that little quirk.

[Jack Dangers]

Mine stopped working too. Even outside with a clear view, I will not get the blue dot. The circle will only show a approx. a 3 mile radius. Trying to restore right now and see if that will help.

[lawrencejob]

I have the same problem since updating to 2.0.1. I tried restoring, but now it spends about 15 minutes getting the location, which naturally murders the battery.

[olisones]

I too am having this problem.

I guess it's something to do with the baseband update?

Has anyone found anything to fix this yet? I've tried restoring the phone and network setting but nothing is working!

[tritonj]

my experience with the GPS so far is it seems to work much faster when i have good 3G reception in Edge only areas it doesn't pinpoint to the street very quickly, while at a 3G area, it takes less than 5s for it to find my exact location

[verks]

The GPS works fine for me when outside because it get a view of the satellite. It's indoors that I have problems. When I'm on 3G indoors it will not find my location using the cell towers and wifi. If I turn off 3G and go to EDGE it works fine indoors. I never had this problem on 2.0 just since 2.0.1.

I met with a "genius" yesterday and he could not give me a clear answer. He said it works and sometimes indoors you can have problems without a clear view of the sky. He did a restore in the store and tried to blame it on my .ipsw file on my computer. It worked about 3 times of the 15 times I tried it in the store. I went over to the 2.0 display phones and they all worked within seconds. That didn't prove anything to him either. I tried to explain to him how it is suppose to work using the cell towers and wifi but he kept going back to his previous explanation.

I hope Apple recognizes this. We will just have to wait for an update.

:mad:

[Macrimonious]

Took about three minutes to zero in with the blue dot, indoors, near windows, full 3G. Then, after zeroing in and having a massive halo, it zoomed me out again and put up the cross-hairs...

[inflynx]

Same here, GPS does not for at all after 2.0.1 update.

[turbo63]

I just talked to Apple support. They have not heard of this issue, but think the phone needs to be swapped. If you have the same problem, they said to call them at 1-800-694-7466 and use case number 103-636-499 . They should be able to help you get a new phone.

[olisones]

I have attempted to use the Location service on both a 16GB and 8GB iPhone 3G with the 2.0.1 software and both do not work. It was working fine on the 8GB model before the 2.0.1 update so I think it must be software related?

Works fine here

[Rybold]

Okay, so a bunch of you are reporting that GPS stops working after installing 2.0.1 . Who is going to be the first person to report back on this thread after going to their local Apple store, looking to see if the demo phones have 2.0.1 and if the GPS still works, and talking to the Apple employees about your newly discovered problem???

[cdd543]

Mine works, but initial lock is slower.

[peskaa]

Not working on 2.0.1 here either, located in London.

Actually, that's a lie. I got GPS working fine with 3G and WiFi disabled, but as soon as I turn 3G on it just spins forever. Tried to turn Location Services on and off, but nothing.

Really quite annoyed at how buggy this thing is now - GPS not working, keyboard still lagging...

[dtheory]

I have the solution... ssh into the phone, replace the "CoreLocation.framework" folder in your pwned 2.0.1 with the one from 2.0, use bossprefs to fix permissions ... works like a charm.... back to the excellent accuracy from 2.0
N.B. I am in the states... on a 2g phone YMMV do this at your own risk

EDIT: seems to work only temporarily... I reverted back to the original files.
rebuilt permissions...

[xraydoc]

Works for me this morning after 2.01 update - though at present I am in a non-3G area, so no 3G signal to potentially interfere.

[olisones]

Would this not mess with the structure of the 2.0.1 update?

[dtheory]

doesn't seem to matter at all...
however, I reverted to the files from 2.0.1 because the effect was temporary
so obviously not a true solution

[ifirth]

UK based - Unable to locate me after 2.01 - either with 3G or no 3G - wireless is ok... use to show this feature off to mates...no left with egg on my face as the wheel just keeps on spinning... how exactly have Apple managed to get this so wrong... I know this is the wrong thread to start this but... Having used macs for the last 20 years the latest operating system the problems I have with my powerbook shutting down under leopard and now the lastest issues with the 3G iphone and 2.0 are really making me ask what the **** Apple are up to... some serious ball dropping going on IMHO

[Neobond]

I'm having this problem with my first gen iPhone, 2.0 locate me worked better than ever, in 2.0.1 locate me only works with WiFi turned off and gives crap accuracy

[inflynx]

So did anyone contacted Apple with this matter?

[MICHAELSD]

Mine stopped working after a few weeks with 2.0. Are the GPSs in almost every iPhone 3G failing? I'll see what happens when I install 2.0.1.

[johnnyjibbs]

I've had some problems too. Occasionally it has worked since upgrading to 2.0.1 but most of the time it struggles. Not half as good as 2.0. Oh dear.

At least it's just a software issue.

[MICHAELSD]

I'm still on 2.0 and my GPS hasn't worked the last few times that I tried to use it, it worked fine when I got it, though. I think that this could be a hardware problem since it's starting to stop working out of nowhere.

[MICHAELSD]

Sweet! I got an article on Engadget about the GPS:

http://www.engadget.com/2008/08/11/iphone-experiencing-gps-problems-after-2-0-1-update/

[Gock]

I actually have the first gen iphone and after the 2.0.1 update, my maps won't work at all now! I bring up the maps, and the maps gui comes up but without any actual maps. It stays there for about three seconds, then closes and goes back to the home menu.

I've tried restarting the phone, clearing the network settings, and restoring the phone through itunes. No luck! It worked fine before 2.0.1 :(

I called Apple on the issue and they said if a restore didn't take care of it, then it must be a hardware problem and I would need to send it in. Problem is my phone is out of warranty and they said it would cost $199 to repair it! I might as well get a new one!

I guess I'll have to go without maps for a while :( hopefully it's fixed in the next firmware update.

[appleMACdaddy]

i live just outside of detroit, mi and since the update i have had issues with the "current location" in my maps gps, it puts my current location in dallas, tx. drive!

[cyberbolt]

My GPS is very sporadic. I'm running 2.0.1 and it takes a number of reboots before it will locate me, if it will at all.

This had started happening about a week before I upgraded to 2.0.1, though, after I did a fresh restore of 2.0. It is very irritating. Drives me mad.

[dwman]

Mine's a little sketchy at times as well. I work in downtown DC, yet the GPS sometimes puts me around Six Flags outside Atlanta, GA. WTF???:eek: What the hell happened to quality control at Apple?

[edpalmer]

Can't get ANY location services working, nothing over wi-fi, cellular, GPS. I've tried all combinations of turning on/off networks (3G, wifi) and resetting the location settings, and from all over London. I don't get ANY location, no little blue GPS dot, no larger cross hair zoomed out... nothing! Just attempting a full restore with a newly downloaded firmware. This used to work perfectly before 2.0.1, i've never jailbroken and with O2 in London, UK

[Ozman712]

After the 2.0.1 update on my phone I have had multiple problems with the GPS not being able to locate me (in a places like outside in the middle of a park, etc). Sometimes it works, but other time it can't find me and just keeps spinning until I quit Google Maps. I hope this issue is resolved soon.

[archurban]

I have no idea why google map pinpoint service is not working after 2.0.1 just like everybody wonders. some people say 'skyhook system is melt down'. but who knows? what's the funny thing is that twinkle, twitter, some apps which need location, they are working well. only google map shows me beach ball of madness. I am not sure but is it something mistake by apple like keeping backup everytime when you connect with itunes? well, backup speed is now way faster though. I guess that apple killed some serious execution code during developing 2.0.1. so I expect that they will update to 2.0.2. it seems true.

[Neobond]

Alight! My super accurate locate me is working again on my first gen 2.0.1 pwned phone!

I have been reading all over the inter-web that it is one of two problems:
- a firmware bug from apple, not very likely since it happens with 2.0 and 2.0.1 users at different time under different conditions
- a Skyhook problem

For me it seems like it is a Skyhook problem, and a very regional specific issue. Some regions have this problem, some don't. And it seem to be being fixed by region. I am in Minneapolis and it just started working tonight, it would interesting to see if anyone else near my area has this problem still, or see what other regions are still effected.

[kobachi]

I'm curious if this is a problem that users of PwnageTool are experiencing. A "legit" 2.0.1 update upgrades the baseband, which is most certainly part of GPS functionality. A PwnageTool update retains the baseband from 2.0.1 (v1.4.5 IIRC). Remember when 2G/1.1.3's "locate me" feature couldn't be used by people upgrading using dev team methods?

If Maps 2.0.1 is expecting to be interfacing with the baseband from 2.0.1 and is instead getting the baseband from 2.0.0...I imagine there could be issues like the ones we are seeing.

[Jack Dangers]

I did a restore on my phone and now my GPS seems to work fine.
I will get the blue dot showing my exact location in about a minute max.

[Joesyuh]

From the very begining, with my 3G iPhone, I have been having GPS problems. It is very inaccurate in the first place. Sometimes it will show my location up to a mile or more off. I understand some of that is due to where I live and the towers and all of that, but isnt it suppose to be more accurate.

But after the update it just went to crap. It takes forever to find where I am and then when it does, it is way inaccurate. The thing that frustrates me is my friend has a blackberry pearl and her phone finds where we are to 3 meters right away. I think the GPS in these was suppose to be way better.

Is this a documented problem with apple yet?

[philrobin]

I have the original iPhone and since 2.0.1 the Location function stopped working completely.
When I was pressing the button, the wheel would spin forever, without even trying to send data.
I had everything, even resetting the iphone without importing any of the previous data... nothing...
I was going to post to moan and then decided to try to use it while wifi was deactivated as somebody said it helped. It did not. But now after reactivating wifi it works!!!! I do not know for how long and I hope the trick will work for some of you.
p.

[JWages]

The day I got my iphone I used the GPS the whole way home and it was pretty damn close.

Then I installed the 2.0.1 and now the GPS will only find me in a large radius. :confused:

[chrisduffer]

I'm having the same issue:
Cell tower triangulation has worked twice in the 20+ time I've tried it
GPS however seems to work fine and locks on pretty quick

This is on a 3G iPhone, no jailbreak, O2 iPhone contract in London.

I spoke to Apple who confirmed it's a know issue at the moment, but were sure it had nothing to do with the 2.0.1 update. The suggested the usual turning off/on 3G, wifi and Location Services and a restore.

[imrtt]

Same problem here. 2.0.1 in Seattle.

Can it be a problem with the network? Perhaps the "assisted" part of AGPS is not working for some reason. Without AGPS, the iPhone has to download ephemeris from the satellites, which takes a long time.

OK, that worked for me. Found me in 3 seconds. Strangely i tried this method before and it did not work. Could as well have been problem with Skyhook.

[pj rage]

This is so weird! It seems like more and more people are having nothing but trouble with their GPS after 2.0.1, but still, mine is faster to grab my blue dot than 2.0, and it also tracks smoother and more accurately. I can't believe more people weren't affected positively like this. I guess I'm just lucky :o

[cherbert]

Mine hadn't been working since the update but then yesterday mysteriously started working perfectly?!?

I really don't know what I did. The only thing I did do was drive from London to Telford.

[jasonyng]

I got my 3G iPhone about 2 weeks ago and the Cell Tower Triangulation (bull’s-eye) and the GPS Triangulation (dot) worked fine with 2.0. It would acquire my position within a couple of minute’s right down to the dot.

I upgraded to 2.0.1 and now the only thing that works is the Cell Tower Triangulation (bull’s-eye). No matter how long I leave it or what combination of radios are on or off, it still doesn’t find my gps location. I did a restore a couple times thinking that would help and nothing.

I jailbroke it wondering if maybe that would help and it does not, still just the bull’s-eye and no dot. I am thinking about exchanging it but afraid I will just get another one with the same problem when I go to 2.0.1. Or do I just wait for another update (ridiculous).

This was all done outside with a clear view of the sky.

Does anyone have anymore information from apple on this or any other ideas on how to fix it?

Thanks

[johnsibly]

My GPS also stopped working after the 2.0.1 update too.

However, I eventually got it working again by doing the following:

Turned off 3G, wifi, and location services in settings
Restarted my iPhone
Went out to a spot with a really clear view of the sky (not easy in London, I had to go to the middle of a park), loaded google maps and hit the find crosshair button
Left iPhone to aquire its position for at least 10 minutes
Turned back on location services, 3g, and wifi


After following these steps my iPhone worked out where it was, and it has been working ever since, locking onto its position within a minute (both through cell towers initially then gps). Hopefully this will help other iPhone users with the same issue!

[Saladinos]

GPS didn't work well OOTB, not helped at all with 2.0.1 update.

Have to reset network settings every time I want to use it.

London, UK.

[d wade]

seems to be working fine for me.

[TJB627]

For me, since the 2.0.1 update, the triangulation seems to work most of the time, however my GPS location seems to rarely work. I flew to Louisville, KY last week and actually needed directions, I waited 5 minutes before giving up and calling somebody to get directions. But after being in Louisville a couple hours it seemed to eventually figure out where I was and seemed to work better. However, now that I'm back in Raleigh, NC I don't think I've been able to get GPS to work since.

[jasonyng]

I tried johnsibly instructions and still only tower triangulation works. Anyone else? I am getting close to exchanging it but am afraid it will be the same problem.

[jasonyng]

Ok something to try quick. I haven't had time to test but it seemed to work this morning:

Turn Wifi off.
Open up maps and let it get the cell tower triangulation (bulls eye).
Double tap the screen to zoom in.
Double tap the screen to zoom in once more and then dont touch it.
Make sure the location thing in the corner is still blue.
Wait 5 minutes for blue dot.

I have no idea if this would have anything to do with it but I did this zooming in this morning and I got the dot in about 5 minutes. It could have just been coincidence. Someone else try it and see.

[jasonyng]

Ok scratch that it must have been a coincidence. I just tried again on lunch and waited 30 minutes and got nothing.

[Greggio]

I thought my "fix" had been turning off the WiFi - turns out that was probably just a coincidence and it now works fine.

What I think fixed it was that I had synched the phone with a NZ laptop - there's a setting somewhere in the General Section to do with region format.

Changed that to UK and now mine works every time.

[clovous]

My iphone was working fine before the update but afterwards, it doesn't update with my emails...its says "checking for mail" but it never updates. I'm in Arlington, TX.:confused:
