Exactly. But I still think that most people will ask themselves "Do I want slow Verizon 3G or faster Sprint 4G? It's the same phone on both carriers, just one is lacking 4G." I want a 4G phone to be my next, so it is a deciding factor for me.
I don't think that many people are really holding out for the GSII.The average person isn't going to switch carriers for one particular phone, especially if there's a similar version for their carrier.
