Today was the first day my RAZR showed At&t instead of Cingular. Strange really. My son's SLVR changed a couple of weeks ago. It might have been because I changed the battery and it went through a complete reboot.
I though the tag was created by reading the sim card, so how can it just change? You'd have to change out your sim. Maybe I'm wrong.My Blackjack still says Cingular, and when I search for a new network it still comes up as Cingular.
