This happens about 1-2 times every day. I use my iPhone, put it to sleep, (tap the top button, no hard sleep, hibernate or anything) and put it in my pocket. Sometimes, at least every day, I go to turn it on, and it is totally non responsive. I push Home, top button, nothing. Totally dead, the only two ways to get it on, is A. plug it into a wall charger, it flashes the Play/pause controls like I hit Home too many times, and takes 1-3 screen shots. Then all is well. THe other way is get a text. I find myself saying Hey, text my phone, its like dead, same things happens as a wall charger, its on, I delete the screenshots, and its fine. I have the latest OS and the Carrier update 3.1 (It locked up before AND after this update). And I've restored. Can I fix this? or do I need a replacement? if so, how do I prove it to the Genius?
