Boom! T-Mobile's version of the Moto X has dropped on the Motorola.com website for $599.99. And with that announcement we can now safely say that since the initial launch on AT&T on August 23rd, we now have all 5 major US carriers...the aforementioned Ma Bell, Verizon, Sprint, US Cellular and now T-Mobile all having availability for the Moto X. Of course only AT&T has access to the Motomaker customizations as of yet...but that scheduled to change this fall when we expect most...if not all of the other wireless companies to follow suit. If you remember we've previously tipped that the price of the Moto X on a service contract is rumored to be dropping by $100 sometime later in the fall around the same time that the wood backs become available for an optional $50 charge. No word on whether the purchase price of the phones off-contract will receive a discount as well however. Ok, T-Mobile fans...who's taking the plunge and getting their Moto X?
