Besides the 8830 and one other Samsung world phone for verizon, those are the only 2 GSM phones. But they dont work unless your out of the U.S. Sprint i doubt will be around long enough to even make the jump.
MAYBE....verizon MIGHT make all their phones capable of going GSM w/SIM outside the states for a more compatable cell serivce... like the 8830.
Who knows......everything is changing daily with technology
