Is your store one of them slated to be sold by Verizon? If it is, then you might want to wait to see who's going to get it. The Alltel store here is going to go to AT&T if all the rumors are true.
Is there a Verizon Store in your Town? If there is, then I would just head over there, port your number over and get your Touch.
Also, and I'm sure someone will correct me on this if I'm wrong. But, Alltel is still going to be Alltel, and not Verizon. They are just going to own the company is all.
