I think it will just add to the market and give more people a choice they didn't have before. People will be less likely to jump to another carrier just to get a certain phone since the 3g iphone can only be used on at&t network over here. I've been waiting on android since it was announced and until a week before the announcement I was looking into an unlocked iphone. My biggest deciding factor was when my Dash started freezing up every few days and I was tired of doing resets.
With the preorder mine will be at my door on 10-22 so I'm counting down the days
