Answer to: Why does my iPhone keep restarting?I have a son who decided to jump in the pool with his iphone 4 in his pocked. He put it in the rice for a few days and the phone turned on, but it would not charge past 4% and it kept shutting down after a few minutes. I managed to do a backup in itunes, because it will resume after the phone restarts and starts up again (you have to have a lot of patients for this) but it would not restore anything because it kept restarting. Well I ordered a new battery from ipod Battery Depot for $22.94 plus shipping of $5.96, I installed the battery then went into itunes and did a restore from backup and everythings works great now. I am a 69 year old lady, and if I can do it anybody can. Good luck.
