Hackers hoped that modifying the iPhone’s bootloader (the program that runs before the operating system loads) could unlock the phone; but this has been proven to be a dead end, as the bootloader code must be signed using a 1024-bit RSA private key used by Apple, as indicated in the information published last week on IRC #iPhone by hackers who are working together for this purpose.
Now the #iphone hackers are working on creating an assembler utility for the iPhone processor. “This is the last big obstacle to solve so that it is possible to write programs for the iPhone”
As they indicate, once they are able to write programs for the iPhone, they will be able to write one that unlocks the phone.
IPhone is locked for use with AT & T’s EDGE network. Unlocking the iPhone will allow the phone to be used with other carriers, including those in Asia and Europe, where the phone is not yet available.
The initiatives to unlock the phone began practically from the same moment that the device hit stores on June 29. In a few days, the hackers managed to bypass the activation function, allowing users to access many of the device’s features, except for its use as a mobile phone.
The first to provide the iPhone activation tool was Jon Lech Johansen, known as DVD Jon, a hacker who has helped develop a utility to decrypt the content of DVDs. Within 20 minutes of the availability of said tool, #iPhone hackers published a second activation tool.
Although hackers have yet to unlock the iPhone, they have made another series of progress. For example, last week a tool was released that allows users to install custom ringtones on iPhone.
