Several iPhone 3GS users seem to be facing a peculiar OS reboot issue ever since their handset was upgraded to the new iOS 4. A thread on the Apple support forum presently houses close to 934 responses from users who seem to be suffering from this issue. Here are some reported cases,
“After about 4 or 5 mins in a phone call my iPhone 3GS reboots itself for no apparent reason. this did not happen before I put the iOS4 update on it. “
“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”
“I appear to be having a similar problem since I updated to Os4 on my iPhone 3GS 32 gig. However my problem is when I make a call and I end the call.. My screen locks up in the sense that the touch screen is deactivated. My home button still works.. But I am forced to force a reboot to get it to work again. “
“Upgraded to iOS4 on my 16gb 3gs with O2 in the UK, get rebooting during phone calls and have lost all my emails, work account and private account, though I get them all downloaded again luckily. Also Bluetooth to car was perfect for the last year, but now get intermittant pairing isues. Then this week migrated to Vodaphone, again rebooted in a phone call, lost all my emails, but again they have all downloaded again. last thing I’ve noticd a few of the apps I have just stop and drop back out to the main icon screen.”
If you are one of those suffering from the issue, one thing is to approach the Apple Genius support to get it fixed or at least get a replacement. If that doesn’t sound feasible, it appears that reformatting your iPhone 3GS (after backing up all data, of course) apparently helps according to this user,
“I have now fixed this problem. Went to Apple Store and “Genius” knew the problem. She said that during the upgrade something interfered with the update and corrupted a file (probably the anti-virus). She said she would “reformat” the phone and restore operating system. Problem has now disappeared. “
