@planetbeing tweeted earlier that the Jailbreak app for A5 devices (iPhone 4S & iPad 2) is getting fixed, it is likely that bugs are being removed from the jailbreak App before it gets released into the wild.
We’re testing & fixing problems with the jb app (that @pimskeks finished the majority of at incredible speed). Still needs to be polished.
Once all the bugs in the flow are worked out, we’ll also incorporate it into the redsn0w GUI (but still leave the CLI freely available too). In order to maximize the chances of the jailbreak working for everyone, the redsn0w GUI will use native Apple iTunes libraries – this technique is slightly different than how the Chronic Dev GUI handles communications, and should provide nice combined coverage for all the odd computer configurations out there.
According to a blog post on Dev Team’s Blog the new jailbreak will be compatible with the following iOS versions.
Firmware:
The supported firmware versions will be:
● iPhone4S: 5.0 (9A334), 5.0.1 (9A405) and the “other” 5.0.1 (9A406)
● iPad2: 5.0.1 (9A405)
