Help atrix keeps rebooting.

unable to use phone,,,,,,,,Atrix keeps rebooting ove and over ..............


Mine was about ten days old today and I returned it for a fresh one. It would go back to sleep three or four seconds after unlocking it, widget and app icons mysteriously disappeared from the home screen and sometimes went missing from the phone completely, on reboot it would revert back to the default wallpaper. In general, it was the most annoying gadget I've ever owned!

The replacement has already hiccuped twice but I'm hoping it was just testing the waters on how far it could push me!
