Video of the iPhone Firmware 1.1.3, with confirmation that the leak is real from Natetrue, famed iPhone hacker. Like before, the update breaks unlocks and third-party apps, patching previous vulnerabilities at the same time.

Jailbreak and activation would be absolutely impossible for the time being. The update breaks AnySim’s unlocks. Logically, you can’t unlock this update using AnySim and there’s no alternative to iTunes for activation. If you want to activate, it will only work using iTunes and a standard AT&T account.
