WiFi iPhone 1.1.3 hack
An over-the-air hack that updates already-jailbroken iPhones to firmware version 1.1.3 has surfaced, allowing users to update their hacked iPhone or iPod touch without a computer. The update takes up to 45 minutes as it silently brings a hacked iPhone up to date with Apple's latest mobile software, downloading the firmware from Apple over a wireless connection, according to CrunchGear. The update only works for iPhones that are already 'jailbroken,' or that allow users to access the filesystem.
Users looking to upgrade must ensure that both the installer.app and the BSD subsystem are up to date. After disabling autolock, users add http://ijailbreak.com/repo.plist to the sources list in Installer and refresh sources. Navigating to installable packages should include 'iJailBreakMobile,' which queries users about which firmware version is currently installed -- either 1.1.1 or 1.1.2.
After selecting the proper firmware version users can run a newly installed application called iJailBreak, which will download the new firmware after confirming that the device is properly set up.
CrunchGear notes that the update is currently incompatible with some third-party apps like Summerboard, and that the update process can look as though the iPhone or iPod touch has frozen or is producing errors.
