I wanted to know this because when I first got my 3G it was jailbroken and I restored it before taking it into the store. They replaced it, but the guy activated it under my PAYG sim? I was shocked and expected them to tell me how I got that sim on there. He had to replace my phone 2x because the 1st replacement didn't want my sim, the 2nd one activated pretty fast and I left the store with a non jailbroken pay as you go iPhone. Has anyone had this happen before?
