With only 10 days left before the great day, you should be speaking to your current network (assuming it's not O2) and asking for your PAC code to be issued. Just got mine from T-Mobile. Unfortunately it cost me a tidy sum because I had to buy out my contract which doesn't end until April 2008. What the hell; I'm just not prepared to wait a day longer than Friday next week. Having said that, good fortune smiled on me in another way. The Customer Service rep, without any prompting from me, halved my monthly charge for my 3G data card (unlimited internet access with my Sony SZ2XP), saving me £120 for the next 12 months. You win some, you lose some!
