It was expected that after the update of Corona, the iBook and launchd fixes would be implemented in the tool from DevTeam. It opens a way for alternatives. If you have already JailBroken iPhone 4, iPod touch 4G or iPad 1 on iOS 5.0.1, you can simply install Corona from Cydia to apply the patches. Otherwise, move to Redsn0w for the same solution. However, both does the same work.
We would advice you to use latest version of Redsn0w if you have recently updated to iOS 5.0.1 and looking forward for an untethered JailBreak. It would help you to get the latest fixes as well as an untethered JailBreak. Thereby, saves you from a little more work which would do by installing Corona from Cydia to make iBooks and Launchd functional. While using Redsn0w second time, uncheck ‘Cydia’ from the available options.
Also, untethered JailBreak for iPhone 4S and iPad 2 is in the works. We are expecting release in few days. Pod2G has also come up with a video where he has demonstrated a JailBroken iPhone 4S running on iOS 5.0.1. Let’s know if you face any problems in the comment section. We will answer all your doubts shortly. Download Redsn0w from the links below:
