After getting FCC'd in July, a 3G'd up version of the Samsung T639 is now on sale at "select" NYC T-Mobile stores. The catch is that T-Mob's 3G network isn't quite up and running—they bought some licenses in 2006 and have been working on it, but it ain't ready yet. Of course, the T639's launch might be hinting it'll be ready to go sooner rather than later, at least in certain areas. Guess we'll know soon enough. Or not. [Phone Scoop]
