Hi, another newbie here. I am trying to leave AT&T and go to T-Mobile. I have an AT&T Samsung Captivate that I want to use on T-Mobile. They sent me the sim card. AT&T gave me the unlock code. I got registered with T-Mobile. Voice & text worked immediately. No internet of any kind, even after an hour or so with T-mobile tech support. I figured (and have read numerous success stories on this forum and elsewhere) that I would at least get edge/G2, but that's not the case. Any ideas? Thanks!
