GPS does not work after installing 2.0.1

dtheory said:
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

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

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.
 
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.
 
wrong "current location"

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!
 
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.
 
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?
 
iPhone 2.0.1 killed my GPS

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
 
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.

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.
 
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.
 
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.
 
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.
 
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?
 
I just fixed it!!!

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.
 
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:
 
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.
 
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.
