T-Mobile's 3G network started going live today, and it looks like that early word from a company memo may not hold true for all users. Some markets may in fact have a silent soft-launch of faster data rates, we've heard from several tipsters who've said that they're already getting faster data service, and now the company itself getting the word out that it's launching data as well. But company peeps were indeed instructed to make sure customers don't count on that faster data being present; bottom line is you may have it, you may not (but if you take T-Mobile at its word, you should). NYC is the first market to light up, but others should come online soon -- anyone trying it out? How's it going? Hit us up in comments and let us know!
