don't forget most of the information is kept quiet some information is spread or leaked. most representatives from any carrier isn't going to know the whole story, excet for what they read on forums such as this, what they hear customers tell them, and what they catch from other employees. So everything is all speculation regardless of carrier.
From what i understand we will be getting the bold just a little later than some other providers, there are/or maybe a few reasons why it will be launchig a little later (besides the rumors that t-mobile is slow with getting new features)
