I had a conversation with Verizon Support on Twitter a couple days ago. The short answer I got from them was as of Sept 30th this year, any unlocked 4g phone should work on any US carrier. This is the first I've heard of this. Has anyone seen any press releases or other are there Verizon people here who can explain more about this? It sounds like a really cool thing! I'd be advertising this if I were Verizon!
