TmoNews has gotten their hands on a seemingly internal T-Mobile doc discussing their imminent 3G plans. As tipped, it’ll launch in NYC tomorrow and 20+ major markets by the end of the year. One thing to note, in the doc it discusses the “great call quality” and “more network availability” 3G will offer, not hot, melty data. Well, we’ve been told that the first phones won’t be using the 3G network for data, but voice only, to offload capacity from their older network. Hence the batch of bizarrely 3G mid-rangers that aren’t exactly browsing or email monsters. Hit the jump to see if you’re gonna get in on this by the end of the year.
