The iPhone Dev Team has been busy from the looks of things. Redsn0w has just been updated to version 0.9.15b1 and includes a hefty amount of new changes. The update includes major features for restoring to older iOS firmware that Apple isn’t signing anymore. Some of the major changes are outlined below via the iPhone Dev Team blog:
- Restore A5 and newer devices from iOS 5 to any iOS 5 firmware you have SHSH blobs saved for
- You cannot restore to older iOS 5 firmwares if you used OTA updating to install a new iOS update
- Redsn0w won't be able to prevent baseband updates of A5 and newer devices
- iPad 2 users can use iOS 4 SHSH blobs for restoring to iOS 5 (if you have iOS 4 and iOS 5 SHSH blobs saved) even when on a newer firmware such as iOS 6
One of the important parts of the update is that redsn0w 0.9.15b1 now installs Cydia on the tethered jailbreak for A4 devices. With the previous version of redsn0w that was used for jailbreaking iOS 6 on A4 and older devices, users would only get an SSH tool, since Cydia was not installed. It was possible to install Cydia manually using a command line interface such as Terminal. The jailbreak continues to be untethered for old-bootrom iPhone 3GS users.
The iPhone Dev Team also makes note that ultrasn0w is not yet ready for iOS 6. That being said, you will probably want to stay away from iOS 6 for now if you rely on ultrasn0w. Redsn0w 0.9.15b1 will not jailbreak your iPhone 5 or iPod touch 5G and it will not jailbreak any iPhone 4S, iPad 2, or third generation iPad running iOS 6 either. The latest untethered jailbreak remains at iOS 5.1.1.
There are a lot of changes in this new version of redsn0w to absorb into your brain at once, but everything is generally straightforward. The updated redsn0w is available for both Mac OS X and Windows – the download links are included below:
