Indeed I think there will be a large migration, but I'm sure that there are hundreds of thousands, probably millions of folks (like myself) who have been waiting for the day Apple teams up with Verizon.
That's a good point. Though all of the anticipation by drawing it out like they have for Verizon has definitely played to both companies benefits. I'm sure it would do the same if they waited a while to transition over to Sprint and/or T-Mobile as well. But ya never know.
Me too, almost four years! It's been worth the wait though! All of my buddies have iPhones on AT&T and watching how frustrated they have been with AT&T's service has helped me remain patient for a VZW iPhone.
