It won't turn on, won't receive calls, charge when I plug it in...NOTHING. I charged it overnight and when I unplugged it this AM it said it was at 100%. Now it won't do a thing. I've tried the hard reset...nothing. I've read that holding the buttons for 10 seconds helps and I tried that with no luck. No matter what I do, my phone does not respond. Some people have talked about their phones doing this and getting hot. Mine didn't seem hot, but I only touched it long enough to carry it downstairs so it may have heated up after I put it down. I have a hard case so if it was hot, maybe I wouldn't really notice it? I'm thinking perhaps I have a bad battery? I have appointment at the Apple Store this evening. If they can't get it going, will they replace it without affecting future upgrades? I am due for one in July and want the 5 if it's released. I'd hate to have to restart a new 2 year contract now. How does the process work? Will they take my phone and work on it for a few days, or will I find out while I'm there tonight if I will be getting a new phone? I hope I am not phone-less for too long. Thanks!
