I want to buy a iPhone but have a blackberry SIM card?

Hi, for Christmas I really want a iPhone 4 or iPhone 5c/5s the problem is I'm tied in to a rolling contract and there's no way of getting out of it without a massive payment, I was wondering if I could use my blackberry SIM card and just but the iPhone hand set? Would it work I know I'd have to get the sim cut but would it work? Also if not does anyone know any ways to get out of a virgin rolling mobile contract thirty pound a month without paying a fee, I have 9 months left!

Just ring your network and request an iPhone SIM and they will send you one FOC. Then you can port your number over if Santa brings you the pressie you want.

1. There's no BlackBerry SIM card. A SIM is a SIM.
2. Yes you could just buy the iPhone, but it would either have to be locked to Virgin or unlocked in order to work
3. No there's no way to avoid the early termination fee.
