Redns0w 0.9.10b3: Untethered iOS 5.0.1 Jailbreak Updated To Fix Problem With MobileSubstrate Based Jailbreak Apps [Updated]

Jailbreak iOS 5.0.1 Redsn0w

Ever since iPhone Dev team released Redsn0w 0.9.10b2, which included a fix for the launchctl issue, a number of readers have reported that many jailbreak apps stopped running after re-running Redsn0w.

iPhone Dev team has just released a new version of Redns0w 0.9.10b3, which fixes the problem. They have provided the following information on their blog:

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).

They also have the following tip for users who may have hit “no identifying data was found” while using Redsn0w:

TIP: If auto-detection fails and redsn0w tells you no identifying data was found, you can always pre-select the appropriate 5.0.1 IPSW using “Extras->Select IPSW”.

You can download the appropriate iOS 5.0.1 firmware file from this link and download Redsn0w 0.9.10b3 using this link for Mac and this link for Windows.

Update:
Some readers are reporting issue with Safari after re-running Redsn0w so please proceed with caution. We would advice you to hold off re-running Redsn0w if you’re not facing any issues and try re-installing MobileSubstrate again as a workaround if you’re having problems with MobileSubstrate based jailbreak apps.
As always, don’t forget to let us know how it goes.
