My wife and I both switched to Sprint two weeks ago and we both got Evo's. Last night she plugged her phone in to charge as we went to bed. About 4 hours later she woke up and her phone was extremely hot and wouldn't turn on. We took out the battery for a few minutes and put it back in but that didn't work. We let it sit the rest of the night and hoped it would turn on in the morning. So the morning came it turned on for about 2 seconds and went black again and hasn't turned on since. Is there anything we can try or do without having to go back to Sprint and get a replacement? Or would it be better to skip all that and go exchange it for a new one?
