I am thinking about switching from Verizon to T-mobile. I live in SoCal (just North of LA). How is the service? I would like to switch to Cingular but their prices seem high. I am thinking about getting an Audiovox 5600 (unlocked) and getting an unlimited data plan for it. T-mobile seems to have some good prices but I don't want to be stuck with poor service. Any advice would be greatly appreciated.
