success! the kind folks at AT&T had no qualms with giving me the 2GB data plan for my captivate. they had to get a legit tablet serial number from the back room to activate the Sim, but all went very smoothly. only problem I see now is that the mobile internet service is horrifically slow. is it possible that i'm not configured to male use of the full 3g capacity of this thing? speedtests are coming in at about 30kbps.
edit: nevermind. 3g kicked in after a few minutes.
here's my configuration for getting the $25 2gb tablet plan working on my unlocked captivate.
