My iPhone was in my pocket when it was raining extremely hard. I didn't think it would hurt since it was in my pocket, but it wouldn't turn on at all..the screen would just go from the apple logo black screen with a line slashed through above or below and then all white and blah. Once I got home, I hooked it up to my computer and it turned on, but once I started doing something it turned off and did the same thing, more quickly, over and over, and comes back on and repeats. Anyone know how I can fix this?
