Hey, I'm new to these forums, so first I'd like to introduce myself: I'm Ben, from the UK, I have a Macbook and the 2G iPhone 8gb. Anyway, over to my problem: I just got an iPhone. A mate upgraded so I bought the old one off him for £100. He just got the 3G iPhone today and of course, he swapped his old simcard into the new phone, leaving my iPhone with no simcard. Went to collect the phone of him a few moments ago and I noticed it wasn't working. He said, yeah, the man said this would happen. It just wont work until you get one of O2's iPhone pay and go sims...but it really isn't working..not switching on or anything. Should this be happening? I just wanna check out the apps etc before I get my sim next week!
