- Does the iPhone replacement battery include the thermal sensor or is the thermal sensor part of the main board? Many 3GS owne...
- You could try to disconnect and after a few minutes reconnect the battery. That theoretically resets the phone BIOS and is supposed to help regarding the reboot issue (see post by NIKKOH007 on page 138 on the Apple forum). Or replace the battery altogether with a newer, iOS 4 compatible battery (like it is offered here). Can't wait for your feedback :)
