Well last night it started to happen sudden random re booting. I went two weeks with zero issues now this. The handset will even reboot during a phone call.. not good. I called Radio Shack, I called Sprint twice then I called a Sprint service center. Radio Shack is no help at all. They said they have no idea when they will ever see another EVO in the store certainly not anytime soon. Sprint C/S said "Were Sorry" Big Help, Then I called the Service center that called the warehouse in Dallas Tx they said they might have a couple in the warehouse but were not positive this is where I'm left now. I did two master resets all no good, It seems that update yesterday might have done something to my phone because it worked fine till about that time. I can't imagine Sprint not putting some phones aside of each batch that comes in for replacements. If you need to do a master reset here are the codes ##786# menu choose reset then put in pass code 535639 touch OK
