Captivate and Vibrant both released in July, Epic released in August and Fascinate released in September. A lot of sites have reported the 3 carriers, AT&T, Sprint and Verizon with models sporting the names that many have been heckling (Function, Attain and Within) but there was never a name given to a T-mobile version. It's personally funny to me how much flak the names are getting because as long as they don't stamp it on the phone, they could call mine the AT&T ass-grab and i could care less... its still goong to work the same. However there is word that T-mo will release a phone in September named the Hercules with multiple specs identical to the S2. If the buyout/merger does occur a phone supporting both company bands would have no problem, theoretically.
