So I had a full battery today on my 3GS. I barely used my phone at all during the day. Got home and had around 70% battery still. I looked at my phone about 20 minutes later (never touched the phone in between) and the battery was fully dead. It's been plugged in for about half hour now and it still wont turn back on saying battery dead.
Anyone know why this happened or how to fix this? Also if it needs to go to Apple (still under warranty), it is jailbroken. Can I restore it if the phone wont turn on?
