The good folks over at T-Mobile always do their best to bring hot new GSM phones to market as quickly as possible. With a subscriber count around 40 million however, manufacturers are seemingly more eager to deal with AT&T and its 80 million-or-so customers more often than not. Keeping that in mind, if T-Mobile can manage to bring the highly sought-after HTC Touch Pro2 to market before its GSM rival, it will definitely be a noteworthy coup. We still have no firm word on when AT&T will be cracking a champagne bottle on the Pro2’s hull but often-rumored August 12th launch date for T-Mobile’s sequel to the aged Wing just got a bit firmer thanks to the leaked sheet above. While pricing is still a mystery, we can assume it’ll come in towards the top of Tmo’s lineup and as such, a more affordable QWERTY option is rumored to become available the following week — the Samsung Gravity 2, another sequel. Though it was officially announced last week, there is still no official word on the pricing or release date for this messaging machine. While the handset’s price still alludes us, it looks like T-Mobile has August 18th pegged for its launch. Hit the jump for the supporting sheet for the Gravity 2 and let us know if either of these upcoming phones will have a place in your pocket and more importantly, in your heart.
