We’ve heard how Nokia is allegedly preparing an exclusive phone for every U.S. carrier and we’re positive you remember the post about a certain “improved” Lumia 900 purportedly coming to other carriers — as AT&T’s exclusivity on the phone is, according to rumors, lasting only 45 days.

Following up on all the above reports and rumors, an in-store T-Mobile rep allegedly said the “Lumia 900 will be coming to T-Mobile this summer”. We could be looking at some real inside information here or just an overzealous sales rep. However, if Nokia wants to really try regaining some of the lost market share of yesteryear, they need Windows Phones on all carriers (yes, Verizon and Sprint too).
