Cult of Mac reports that Apple is in serious talks to bring iPhone to T-Mobile this fall, possibly as early as September.
Cult of Mac quotes a source saying the deal is 80 percent likely. This rumor is interesting because unlike Verizon -- the popular iPhone is coming rumor company -- T-Mobile uses a network chip similar to the one used at AT&T. Unlocked iPhones have run on T-Mobile's network, with slower data speeds, for a long time.
Rumors persist of Verizon and Apple joining forces in January, but a T-Mobile move might be easier.
For the consumer, a move would be good. T-Mobile has cheaper plans than AT&T and any iPhone carrier choice would make AT&T react with better pricing.
