Defiantly but now all the carriers are at war more these days buying out device payment plans and such since there are much contracts anymore.
Not going to say that your comment doesn't have any truth behind it but, with two-year commitments going by the wayside and manufacturers starting to offer their own payment programs, I wouldn't be surprised to see all of the carriers upping their customer service games. Four of the five lines on my account can be ported to a new carrier with a simple phone call. Even the largest carrier can fall very quickly if it makes bad pricing decisions.
