I made a step today for the A5. With some luck we could expect a release in a week.For who don't now, iPad 2 can be only jailbroken on iOS 4.3.3 with the help of Comex JailbreakMe 3.0, which has been patched on iOS 4.3.4 update, since then, there's no hacker could jailbreak iPad 2. But iPhone 4S has not been jailbroken ever.
As before, we are expecting that iPhone Dev-team is involved on iPhone 4S and iPad 2 untethered jailbreak on 5.0.1, consequently they would release new version of Redsn0w 0.9.11 b1 to untethered jailbreak iPhone 4S and iPad 2 on 5.0.1.
Update 1: For who asking to update their iPad 2 or iPhone 4S to iOS 5.0.1 or not ? Pod2g has just answered this question, Pod2g advised iPhone 4S and iPad 2 users to upgrade their devices to iOS 5.0.1 to get untethered jailbreak next week.
