Just blogging this in case someone else if having similar problems. Ron got a new black Razr phone and it kept turning itself off. He eventually called the local Cingular store and (after looking up the phone’s serial code) they said that there was a batch of Razr phones that had a glitch where they’d turn themselves off if they lost a signal. He got the replacement phone today.
In case others misspell: Razor, Razer, Rasor
