AT&T also took over the Alltel towers in eastern Montana. And as a Verizon dealer, I couldn't be happier, because most people have been porting their numbers over to Verizon because they don't want to go to AT&T!!
Perhaps a similar effect will happen when ATT takes over Tmo. Perhaps Sprint will have a ton of new activations. People will buy up a lot of the EVO 3D's, and whatever else Sprint will have by the beginning of next year.
