Iphone 4 from Orange (contract)

OK, finally bit the bullet and ordered my Orange iPhone 4 yesterday. I have a question concerning the micro-SIM though. Obviously I want to use my current SIM from my Nokia, but how do I get it down to size? Do I just take a hefty pair of scissors to it? Do they provide a new SIM, or a tool to resize?

Not possible i'm afraid you will have to ask your supplier for a micro sim or an additional micro on the same number..

Seems like an okay guide to it. I'm sure if you call them up they will send you a new microsim though
