I am currently using the iphone and I am pretty tired of it. I really want to switch carriers and get the upcoming Tour 2 for Verizon. And because I don't get 3G where I am at and Verizon does. But, I am worried about how the transition will be from having used an iPhone for so long. How soon (if ever) will I adapt to the QWERTY board and how soon will I get use to the OS?
