Forgive me if this has been dealt with elsewhere but I've tried a search without any success. I know that with the iPhone 2G the phone worked with a Simplicity sim if the iPhone was jailbroken, and more recently I think, even if it wasn't. I'm pretty sure that I read somewhere that the new PAYG iPhones (3G) will work with the Simplicity sim, except that you won't get Visual Voicemail or Call Merging. I need to know for sure so I'd be grateful if anyone could post a definitive answer. Does it work? What are the limitations in functionality, if any?
