Closely following the release of the iPhone JTAG team’s hardware unlock, the iPhoneSIMfree.com team have officially found a way to completely unlock the iPhone via software. The unlock has been confirmed by Engadget’s Ryan Block, who also shares some details regarding the process, which apparently takes “only a couple of minutes.” The unlock, which will be commercially available starting next week, has been verified to allow non-AT&T access to all iPhone functions, except for Visual Voicemail. The unlock has also been shown, thus far, to be restore- and upgrade- resistant. In addition, the unlock allows access to several hidden menus, which were reportedly added in the 1.0.1 update.
