What is the process to unlock an iPhone 4 once I have the unlock code
I'm leaving work but keeping my iphone 4. Thet have provided me with a PAC details to keep my number and given me an a five digit unlock code. What do i need to do with this ? I'm waiting for a new sim card to arrive which will be using the O2 network. My Company service was Vodafone. What do I do when the new sim arrives. Not sure whether I should take the old sim out then synch with itunes or what to expect from itunes when I do this. I just want to make sure I do everything in the right order and not loose anything on my phone if possible. Many thanks for any help.
