After Engadget, an independent consultant demonstrated on CNN how to hack the iPhone SIM with iPhonesimfree application to be released soon. Once the application installed, all functions are accessible beside push mail feature as it requires server support from the mobile phone carrier. It took only 2 minutes for unlocking the iPhone.
CNN published parts of an interview of two members of the iPhonesimfree developer group, who wish to remain anonymous. They said they would start selling the software as soon as their online payment and customer service systems are ready, but they are also waiting for additional information from their lawyers for obvious reason. Indeed, if modifying the iPhone turn to be legal, it will not prevent iPhone owners to pay the 2-years subscription fee to AT&T. So, it will be a matter of cost at the end.
On the other side, European carriers might revise their position with the iPhone if a true easy unlocking application is legally available on the web.
