Had my Atrix 4G since March 2011 and it's been (mostly) wonderful. Rooted, but still running Motorola GB update. Over the last 9 months or so, it would randomly reboot at strange times, especially if I were ever outside of California. A couple weeks ago, it started doing this again all the time, until one morning it was no longer responsive. I have no reason to believe that the battery was dead, since it was at about 80% the night before. I can't plug it in to anything to get it to turn on or respond. I've been using my Palm Centro for the last 2 weeks and would love to have a working Android phone again.
