Since the iPhone was released, various reverse engineers, hackers, and entrepreneurs have been working night and day to make the iPhone work on networks other than AT&T. Considering that the iPhone was only released last week, progress has been substantial. While individual reverse engineers can get all functions other than cell-phone to work, UK-based Uniquephones has gotten much farther. With their crack team of scientists, they have developed a pre-release crack that activates 75% of all Apple iPhones...without signing a contract with AT&T. An open beta is "almost ready", and the full version should be $50 USD. A fully operational retail version of this software would effectively allow an iPhone to be used with any network (Verizon, Sprint, and others).
