iPhone 3GS restarting itself

[kcheleb]

Hello everyone, I'm new here and I apologize if this is not the proper place to post this .. I would like some help please

I have an 8GB 3GS iPhone with iOS 5.0.1 installed,
Lately I’ve been experiencing a problem with the iPhone that I noticed started when I installed iOS 5.0.
I thought updating to 5.0.1 would fix it but it hasn’t and the problem is still there

Basically my problem is that the iPhone keeps restarting/rebooting itself every 5 or so minutes. What’s funny about this is that this ONLY happens when I’m in this one area…my classroom in the basement at school
Whenever I am anywhere else the phone does not do this. However, as soon as I go to that classroom my phone will start restarting/rebooting itself every 5 minutes. One thing about that classroom is that I get absolutely no signal there, or if I am lucky then I may get 1 bar for a few seconds before it disappears.
This problem is really driving me crazy and I’m not sure what to do. I tried restoring the iPhone but that did not fix the problem, and like I said I updated to 5.0.1 and hoped that it would fix the problem but it hasn’t.
When I was on iOS 4 this problem never occurred
NOTE: my iPhone is not jailbroken, I have not jailbroken it with iOS 5 or 5.0.1

Anyone have any ideas or suggestions? Anyone else experiencing this problem?

DFU Restore and don't restore from a backup.
If it continues happening send it in for a replacement.

Just an update on the situation. When I went to class today I put the phone on airplane mode before going in and the phone still kept restarting during class

When I left class I turned airplane mode off and the phone restarted maybe 1 or 2 times after that and then it was fine, stopped restarting ...

Also, my phone isn't under warranty so I wouldn't be able to take it to Apple

My 3Gs does this as well, though not with the same frequency. It also started when I updated to iOS5 and hasn't stopped since the update to 5.0.1. Mine doesn't seem to be tied to any specific location, but the amount of signal may have something to do with it. Whenever I lose signal and it says 'searching,' if it does that for more than about 30 seconds it will shut off and reboot.

My iPhone 4S and iPad 2 were both doing this the other day. I was copying a lot of stuff onto both of them and they both started restarting or crashing to the homescreen.

Just another update on this situation actually, when I put my phone on airplane mode .. the phone starts restarting itself as well, and this happens no matter where I am. If I put my phone on airplane mode at home for instance it will begin restart itself just like it does in that classroom where I have no signal. This problem definitely lies with the signal .. it seems like 0 signal causes the phone to restart every 5 minutes ..

I don't know why people are so quick to tell others to 'send it off for a replacement'.

this restarting problem isnt the hardware, its ios 5 and its huge list of bugs. it happens all across the board, 3gs, 4 and 4s. havent paid attention to the ipads.

i went through 6 4s (for other reasons), and noticed almost all of them did it. its got to be a certain variable in the set up of some people, because it doesnt do it to everyone. i had 2 replacements that i didnt notice do it, but i didnt even have them for a whole day, so im sure they would have done it eventually.

you can check the diagnostic screen for the crash log.

My iPhone is no longer under warranty .. I am not sure what to do

When I put my iPhone into airplane mode it starts restarting itself as well

Doesn't it cost $30 just to speak to someone over the phone for Apple support?
