As we eagerly wait for pod2g to release the untethered jailbreak for iOS 5.1, the iPhone Dev team has quietly updated Redsn0w, which includes a number of new features including the Corona A5 untethered jailbreak for iPhone 4S and iPad 2 still running iOS 5.0.1.

Redsn0w 0.9.10b7 includes the following new features:

Corona A5 untethered jailbreak for iPhone4S and iPad 2 still running 5.0.1

It can also re-install that jailbreak for those who accidentally uninstalled the untether.

When stitching an IPSW, it can now grab your blobs directly from Cydia.

It now shows a lot more info about your device (for instance, whether your iPhone3G has the vulnerable baseband boot loader, or whether your iPhone3GS has the old exploitable bootrom.

Dev team has also revealed that they plan to add built-in restore support in Redsn0w, to provide an alternative to iTunes restores, which will be a killer feature as it should be able to avoid those annoying errors when you try to restore using custom iOS firmware files using iTunes.

Redsn0w 0.9.10b7 can only perform a tethered jailbreak for iPhone 4, iPhone 3GS (expect iPhone 3GS with old bootrom), iPad 1 and 3rd-generation iPod touch on iOS 5.1, which means that you need to connect your iOS device to the computer on every reboot. So if you’ve jailbroken your iOS device running on iOS 5.0.1, you are better off avoiding the iOS 5.1 software update, which doesn’t include any major feature.

if you’ve accidentally updated your iOS device to iOS 5.1 then you can use Redsn0w 0.9.10b7. You can download Redsn0w 0.9.10b7 using this link for Mac and Redsn0w 0.9.10b7 using this link for Windows.
