Just got my 6th referb TB today.. Every phone a new problem , from camera not working, nothing above 1G, screen freeze,buttons not working, no data connection at all etc etc .. Put the old sim card in and screen un responsive...To those who lucked out and got a good one cheers! To those of us stuck in the certified referb loop keeps our heads up we will get a good one someday.. They need to throw away the returns and stop sending them back out to us. A nice piece of plasic on the screen doesnt make it "like new". Find out what the problem WAS than fix it test it and than certify it. I think most of the time the techs dont know what the problems were and test a few things put it back in circulation. Cant wait for the Vigor or Prime I hate the HTC Thunderbolt. So done with it. Is this phone the worst HTC phone made?
