Is T-Mobile Going to be the Fourth iPhone Carrier in October?

According to T-Mobile, they already carry over one million iPhones on their EDGE network. If Sprint is really joining AT&T and Verizon as an iPhone carrier in October, Apple should let T-Mobile customers experience something better than 2G speeds.

MacTrast talked to a T-Mobile employee who claims Apple does plan to let T-Mobile users out of their 2G jail cells, by offering an iPhone 5 that would operate at 3G speeds on the T-Mobile network.

Yesterday’s Sprint rumor said that the carrier would also be offering the iPhone 4 on their network. The MacTrast tipster made no mention of an iPhone 4 for T-Mobile.
