Just recently (yesterday, to be exact), we mentioned that the upcoming redsn0w release will allow you to downgrade your iOS for untethered jailbreaks, and the day has arrived. The brains over at the Dev-Team have managed to put together a nifty piece of work, where they intend to make your jailbroken iOS experience take the easier road. The latest version of RedSn0w now stands at 0.9.11b1, where you can apply it to the new iPad, iPad 2 and iPhone 4S in order to perform a downgrade to lower firmware versions. Now, a very good question to ask now would be this – why would you want to do that? Why, the answer can be said to be a no-brainer – it is meant for jailbreaking purposes, of course! Of course, the necessary still needs to be done beforehand, where you are required to have those saved SHSH blobs from the previous firmware, and supposing your iOS device relies on an unofficial unlock, you would do well to stay away from this method as it will upgrade your baseband. Definitely does not sound as though it is for the faint hearted.
