Four sites have already gone live retailing the iPhone unlocking. Here in the US we have Wireless Imports, then in Australia there is iPhoneWorldwideUnlock which presumably works worldwide, and they are the cheapest too, then there is 1digitalphone from Germany, and iPhone4arab in Saudi Arabia.

The US retailer is charging $99 with the Australian one charging a mere $50. Other than price, the difference will likely come as soon as AT&T’s legal team gets wind of this new update, and then the US retailer will probably be taken to court.

I wonder how long it will take someone to reverse engineer the code for this software based unlock and release their own version for free. So now that you know about this, and the retailers, I want you, the readers, to let me know if you try this and whether it worked or not.
