The long-awaited untethered jailbreak for all A4 devices running iOS 5 or iOS 5.0.1 has finally arrived, in the process giving users of Apple devices running on the A5 processor hope that their break is around the corner.

The break, based on pod2g's exploits, was discovered a couple of weeks ago and since then both the iPhone Dev team and the Chronic Dev team have come out with the required tools for an untethered jailbreak.

Hello, as expected, the Chronic Dev Team and the iPhone Dev Team have released the A4 untethered for 5.0.1 based on my work, pod2g wrote on his blog.

The two new untethered jailbreaks - the Chronic Dev team's Corona 5.0.1 and the iPhone Dev team's Redsn0w 9.10b1 - are compatible with A4-powered devices like the iPhone 4, the iPhone 3GS, the iPad, the iPod Touch 4G and the iPod Touch 3G. However, both jailbreaks lack a bootrom-level exploit, which could lead to jailbreaking A5 devices.

Redsn0w 9.10b1 was followed by 0.9.10b2 which fixed a launchctl error. In a bid to fix more such issues, the iPhone Dev team released another update on Friday.

Many users, who had already overwritten an earlier jailbreak and stepped into the puffed-up untethered jailbreak world, have been facing a number of crashes due to MobileSubstrate-based apps. MobileSubstrate is a key element of most of the better Cydia tweaks and apps.

To fix the issue, a third beta of Redsn0w - called Redsn0w 0.9.10b3 - has been released for both Mac OS X and Windows.

The b3 version of redsn0w fixes a problem where re-running redsn0w over an existing jailbreak would cause MobileSubstrate-based apps to stop running until MS was installed again. Now you can re-run the redsn0w jailbreak step without worrying about that (but still remember to de-select the Install Cydia option if it's already installed), the Dev Team said in a blog post.

According to a Redmondpie report, if RedSn0w cannot properly identify the data of your auto-detected IPSW, you are required to manually select your device's 5.0.1 IPSW by navigating to Extras > Select IPSW in Redsn0w's menu.
