my question is... is there something that apple did to the 2g iphones that would only allow a certain number of computers that you can setup itunes for with a single phone? let me clarify.... person 1 - buys iphone 2g, sets up itunes and activates the iphone. person 1 then sells the phone to person 2. person 2 - uses pwnage to JB the iphone, uses itunes with this phone. person 2 then sells to person 3 person 3 - inserts sim to phone, hooks up to itunes. now decides to sell the iphone.... how long can this continue? is there any restriction about this???? need to know, i will be getting a used 2g this weekend.
