Ive been keenly keeping up to date on all threads for unlocking the iPhone. I haven't received mine yet but I purchased one with all intentions of unlocking immediately. To be frank, it is exhaustive with all the errors, guides and how quickly things are changing.

Thankfully, Macworld may have come to our rescue with very clear instructions for the macolytes. I have not tried it myself since I do not have my iphone. But this is one source I would quickly trust. Here's the link: http://www.macworld.com/2007/09/secr...king/index.php
