ok guys, sorry if this was already posted but I am wondering what will happen if you want to buy a 3g iphone and use a new number, and keep your old plan with iphone 1? will the rate stay the same for the edge based iphone or will that go up also? also, an unrelated question about text messages. do we get charged for receiving text messages or just sending them? I know how to send them for free so could deal with not having texts in my plan... if we do get charged for receiving, is there a way to block getting texts?
