iOS4 update - now iPhone now reboots during phone call

I have got the same problem over here, i took the following steps:

- Upgraded from 3.1.3 to IOS4
Got a 29 error, but fixed this with some magich (irecovery)
- After this i got a working copy of IOS4 on my phone, i restored my last backup.
- Phone suddenly crashes even in standby.
- Did a restore and made a new profile.
- Now the phone only crashes while calling.

I hope we are not the only one with this issue....

Same here, although this 32Gb 3GS has always been a bit flakey from new, rebooting spontaneously now and then.

I did a normal upgrade, then a full restore and still it reboots during calls.

I've a Genius appointment tomorrow, hopefully they can swap it out to solve it.

I just upgraded my phone literally three minutes ago and I hope I don't have this issue also, it took my phone about 3 hours to back up and I don't know why.

I also have this problem. Incoming call, answered it, suddenly rebooted in the middle of the call.

Me too. Had one 18 minute incoming call since upgrading today and one 7 minute incoming call - both OK. Then just now it rebooted in the middle of a call. If this happens again the phone has ceased to be fit for purpose.

I have exactly the same problem, and it's driving me crazy!
Phone reboots after >5 minutes in the call
Please give us a fix!

Could it be related to memory usage with the new multi-tasking? It only happened to me later in the day - maybe the amount of available memory had dropped too low. Is there any (non-jailbroken) way to see how much memory is in use?

Mine can do it twice in a call and so the second time, having rebooted, with no apps on the device the memory should have cleared therefore I would imagine it's something in the hardware as it's also a minority of users it seems, some part marginally out of spec maybe.

Did a complete restore this morning and still happening to me. Longest call I've managed so far today is 6 minutes.

I take it back. Just happened again after a reboot. Has anyone had it happen who did a restore followed by a setup from new? No settings, etc from a backup?

I have a 32 GB 3GS, and it seems to reboot about every 4 min. I am not happy!

Did you restore and then recover from backup? Or did you set it up as a new phone? Also, my phone was jailbroken before the upgrade. Has anyone had this problem who wasn't jailbroken?

Yes. Get the app iInfo on the app store. It is free and works great.

Did a restore from backup earlier today which had no effect, just done a complete DFU restore and setup the device as a new phone. Will see if this makes any difference.
