It seems like we've been waiting for this for ages: according to the latest rumors and leaked documents, T-Mobile USA will finally launch its oft-delayed 3G network [1] in New York City tomorrow, with 20 more markets set to launch before the end of 2008. Now here's the rub: it's not going to be a data network, at least, not at first. The leaked document promises that the new network will deliver the "great call quality [customers have] come to expect...and more network availability." This seems to fit, given that all of the 3G phones we've seen on T-Mobile so far [2] aren't exactly data crunchers but one would assume that if the company is rolling out 3G voice service, 3G-enabled smartphones and data plans can't be far behind.
