Signal is /constantly/ dropping on iOS 5

Take the sim out for a minute, pop it back in, see what it does. If that fails, try a restore again.

 

OP, what baseband are you on? I've been hearing a lot of people have issue with the 1.59 BB. I want to upgrade my BB to a newer version to fix this issue but I'm waiting for someone to confirm I could still have an untethered jailbreak on 4.3.3 with BB 4.10 (no carrier unlock needed)

 

I was just wondering, were you previously on 4.3.3 and had a full untethered jailbreak? I want to upgrade my BB and still have an untethered jailbreak.

I could report in once I upgrade BB and update to iOS 5

 

Thanks, I'll be updating to Stock 4.3.3 to upgrade my baseband later today and doing the untethered jailbreak and if I get that working then I'll be upgrading to tethered iOS 5 and see if I can get MMS/3G and calls working fine.

 

I am having the same problem! Please help. I can't get past this issue.

 

Noticing this too, although I'm in a pretty marginal/fair signal area to begin with. It definitely drops AT&T far more frequently than normal, doing the "Searching..." to "No Service" to a couple bars on a pretty regular basis. Seems the new baseband is indeed different...

 

Upgraded to 4.3.3 stock (letting TinyUmbrella upgrade baseband) and fully activated with that. Checked out my BB, was successfully updated to 04.10.01.
Ran Snowbreeze to custom IPSW for iOS 5 and preserved baseband and successfully activated on ATT.

Currently have 3-4 Bars, ATT is registered, 3G is working flawlessly and no issues with MMS. Looks like a successful upgrade (tethered obviously)

 

Not your "only" but it may be the easiest one.

You can use your GF or anyone else mac to do the restore, you don't need your data on that machine, you can do the restore and once it finish sync it to your machine and restore the backup, then go back to the mac and do the JB,,,or you can restore and JB and then restore your backup on your machine after the fact, it will also work.

 

Same situation here. I have a 3GS on IOS5 BB6.15 and my signal keeps dropping as well as my bluetooth. A temporary solution is to turn off your location services. My signal has been good since. I hope the dev team or someone else figures out a permamnet solution.

 

I have had this signal drop problem I think from the time of iOS 5 Beta 6..(it didn't happen after upgrade.. it suddenly happened after using Beta 6 with no issues for a week or so..) none of the Beta 7 or GM or final release fixed this, and it still exists.

My iPhone 4 was never jailbroken either.. and I have gone through many resets, hard resets, restores, or "set up as new iphone", yet with no luck whatsoever.

Any suggestions, I would kindly appreciate it

Edit: Some details:
iPhone 4 on Rogers Wireless network
Software: 5.0 (9A334)
Carrier: Rogers 11.0
Modem Firmware: 04.11.08

 

This happen to me too when I was playing around with my phone.

What happened was I turned on Location Services and my phone started to disconnect from wifi and then reconnect, and then loose all my reception, and then back again.

Turn off Location settings and it might work again.

And keep it off...

Alternative

You can try the new sn0wbreeze for windows users

Location Services had no effect on the issue for me... Plus, we shouldn't have to "sacrifice" a feature to gain another one..

What sucks is that this started happening about one week after my 1yr warranty was over.

 

Here's a new one for ME at least

I got a 3GS from my brother in law, who never jailbroke or unlocked the phone. Well, long story short, I did jailbreak, and I flashed the iPad baseband over into the iOS 5 update, unlocked using ultrasn0w, and everyting as far as signal works fine, except THIS... ANY time I go into facebook, foursquare, or what seems to be ANY app, except for cydia or the app store, my signal goes into searching, and then no signal, and I actually lose my WiFi connection as well. I dont know if its an issue with the location service being used for apps like facebook and foursquare uses or what, but it is SERIOUSLY confusing me. Ive even tried restoring and doing the process all over again and still no luck. I dont know what else to do, but this SUCKS!! Any help or ideas would be AWESOME

 

See if you have time to add AppleCare yet...mine allowed it past the actual expiration of my 1-year warranty (from actual purchase date) seems they had added an additional 45 days roughly...you may still be able to extend it...

Back on topic, I'm still experiencing weird signal, even in strong signal areas. A lot of 1-bar to full service to 1-bar etc which never happened before. There's definitely something amiss...

 

I have the same problem, were you able to solve it?

 

My warranty was until Mid August.. so are you suggesting that I purchase an AppleCare box and try to activate it for my iPhone? BTW, when had you bought the AppleCare (not when you activated it), cause it might be that purchase date was before your warranty would run out, so they let you add it?
