My US iPhone arrives tomorrow (Im in the UK). I use a Mac, with the latest patches, iTunes etc etc. What jailbreak/ SIM unlock method do I need to use? I'm not sure what firmware it will be on yet, but I doubt it will be 1.1.1 A link to a guide for use on a Mac would be great. I can run the unlock on Vista, as long as I can use the Mac as my main iPhone computer.
