The iPhone Dev-Team has recently updated its redsn0w jailbreak tool, adding a new injection feature and making a variety of bug-fixes, according to the Team’s website.
A couple of weeks ago, the combined effort of a number of iOS hackers – and most notably, @pod2g – resulted in the release of Absinthe 2.0, which has the power to jailbreak iDevices (including ones powered by the A5X processor) under iOS 5.1.1. Now, the Dev-Team has made redsn0w 0.9.12b2 available, with changes including a new rocky-racoon injection option and an iBooks bug fix. Here’s the release notes, as outlined over at the Dev-Team’s website:
Update #1: Starting with version 0.9.12b2, redsn0w will now explicitly ask users with limera1n-able devices whether they want to inject rocky-racoon using the DFU ramdisk method or the backup/restore method (the ramdisk method is better for those with lots of media on their device that would create very large backups, and it’s required for those with unactivated iPhones). If you’ll always want to use limera1n, you can select that in the Preferences pane. It also fixes an iBooks issue on old-bootrom 3GS iPhones, and provides more useful error messages when things go wrong.
You can download redsn0w 0.9.12b2 from the iPhone Dev-Team’s website, or via these links: redsn0w for OS X, redsn0w for Windows (run in Administrator Mode). The Team’s website also hosts a number of other tools, including PwnageTool and cinject – with ultrasn0w, an unlock-tool, being available from the Cydia Store itself (for free).
