My turn came up in the OTA updating to Froyo on my Evo and I was totally psyched. I went through the standard steps of downloading, installing, etc. It seemed to be fine once the final restart happened. Was running what I felt was smoother and I was loving the landscape option for holding it either way but in the midst of checking my email, the screen shut off. I just thought I hit the power button by mistake but it wouldn't turn on. So figuring it was out of juice (a likely thing to happen considering amount of use it gets) I plugged it in and I got the blinking orange light rather than the charging light and it still wouldn't turn on. So in a last ditch effort (sfter scouring the internet for answers) I unplugged and took the battery out waited a few minutes and reassembled the phone. Still nothing... Now as a note, I haven't installed anything unofficial nor have I rooted my phone so I know this wouldn't be an issue. I did heed the warnings on the previous update in June and kept putting it off, eventually hearing about the Froyo update and figured I do that one. So here I am with my paperweight and I'll be heading to the Sprint store this afternoon (already called and said no problem they'll fix or replace it). Just a warning to others that it has happened but doesn't seem to be common. Good luck to all you other Evo owners.
