Well, he told me that a Microsoft rep told him that T-Mobile had a 45 day exclusivity on the DVP starting from the launch date (11/8). Further, the DVP will be on 3 carriers once the exclusivity runs out. Now the speculation on the other two was Verizon and possibly AT&T.
He also said that the 3 WP7 phones at AT&T were under the 45 day exclusivity as well and that other carriers would be carrying the three devices currently at AT&T.
He wasn't sure if and when all this would happen but if in fact AT&T will be getting the DVP soon, I can hold out a bit longer as the only reason I was planning on switching to Tmo was for the DVP.
Don't mean to start a wild rumor thread but thought I share what I heard and would like to know if others have heard something similar.
