After several days of quiet, both iPhoneSIMFree.com and iPhoneUnlocking.com have posted new information for potential customers awaiting the release of their iPhone unlocking solutions. iPhoneSIMFree.com, whose unlocking procedure has been verified by Engadget, has posted a FAQ concerning its software, which it hopes “to release in the next 48-72 hours”. Addition details reveal that the software will require a “jail break” of the iPhone, and that the device must be activated for the software to work. iPhoneUnlocking.com, meanwhile, has uploaded a video demonstration of its unlocking solution to YouTube. The video shows the iPhone being unlocked using a Windows machine, connecting to a Mac, and making trial calls. iPhoneUnlocking.com’s parent company, UniquePhones, was contacted by AT&T lawyers over the weekend concerning the release of its unlocking software.
