Easy Unlock with iUnlock...

There have been a number of solutions that have come out since I started this blog, but iUnlock appears to be the best and cheapest (FREE). Developed by the iPhone Dev Team, it's not (yet) for the faint of heart and it takes a little longer to do its magic than iPhoneSIMfree's method, but it works. Download the ZIP archive HERE. (This version may not work with iPhone 1.1.2 update.)
