I installed iOS 4.0 a while back and has been working fine. But last night my phone started frequently crashing. If I have any app open I can use it (the app) for a while then, it will go to a black screen for a couple of seconds, then return to the home screen. I thought it was a Safari only problem, as that is what was open when the problem started, but it does it in all apps. It also occurs both with Wi-fi on and off. I have searched the net and tried everything suggested (hard-reset, soft reset, turn phone off for a few hours, clear cache, clear cookies, restore, etc) but to no avail. On top of this the phone has now started running hot on standby (with nothing open) and the battery life can go from 100% to 40% is just over an hour. Can anyone help or suggest anything before I make an appointment with the genius bar?
The phone isn't jaibroken, and has never been. Thans for any help in advance
