i've had an iphone 3g, 8gb for about 18 months. the phone has fallen a couple of times, but it was always fine. over the last two months, my iphone has been getting the white screen of death. usually i would press the home and top button till i saw the apple and it would restart itself and be back to normal. but last week, i pressed the home button to wake itand it got the white screen and no matter how many times i pressed the top and home buttons, it wouldn't restart. it just went black. i could hear my texts and phone calls come thru, my ringer was working. i plugged it to itunes and it recognized it and was able to back it up(it took like 8 hours to back up, maybe because it was messed up or because i had a lot of apps. i don't know). i was able to restore it like a new phone and i wiped everything off the phone. it still didn't start up. i figured i had broken the phone somehow, like the lcd thingy(i'm not very tech savvy) or something. i left it alone and after 3 days of not turning on, it started up and i was able to reboot it. it was completely wiped clean when it started up. the screen is crystal clear with no grey/black lines on it like nothing happened so my question is, do i have a broken lcd thing or could an app i had on the phone caused it? please help. btw, i'm extremely happy it was able to restart itself.
