Well here is the story. I want to trade this guy my iPhone for his Droid Razr and that is all fine, but I was wondering how it would work if we both are currently using the phone. I use my iPhone and he uses his Razr. So could we just go to the Verizon store and swap our numbers and service to the other phone since we both have Verizon? I know if you have an active phone you can just switch to another inactive phone but both our phones are active right now. Could someone tell me how this is going to work or if there is any problems that could arise? Thanks!
