T-Mobile has had a longstanding tradition of giving current customers first dibs on pre-orders for hot products, and it looks like the upcoming G2 will be no exception. TmoNews has a rather telling screen shot suggesting that T-Mobile subscribers will be able to sign up for the Android-powered QWERTY slider starting tomorrow through October 4, with retail availability following a couple days later on the 6th; we've already had that date on lock through Best Buy Mobile, so it comes as no surprise. From what we've seen so far, the G2 and the Desire Z are pretty easy to fall in love with -- trust us when we say the hinge mechanism is exquisite -- so who's signing up tomorrow?
