So I have a 3gs 32 gb & a 9000(bold) both are great and under my family plan. My question(s) is that I want to switch my sim from my 3gs to my bold so I can keep my original # from my bold. By switching the sims and calling AT&T to confirm that the numbers where switch I would like to cancle the new line which I had for the 3gs but now will be using it for the black berry. Am I going to get hit over with the Orginal price of the iPhone (even though I switch the sims and numbers over?) I don't care about. The ETF I'll pay it.
