My wife and I both have a 3Gs running 3.1.3 and they are both Jailbroken. As of about a week ago they would both start shutting off for no apparent reason. Mine goes blank and the only way to wake it up is to hold the power and home screen and then releasing home until it starts up. My wifes will turn off and she only has to hold the power button until it turns on.
Last night hers shut off again when it had a full charge - but then when she got it on the battery showed dead. She plugged it into a charger but it wouldn't charge. We ended up doing a restore on hers and set it up as a new phone (not from a backup) with the 4.1 software and didn't JB it yet. I thought for sure that would fix things.
This morning hers shut off again while using it.
Any thoughts??
