iPhone Dev Team has updated Redsn0w to the version number 0.9.10b3 to jailbreak Untethered om iOS 5.0.1. First iPhone dev team released Redsn0w 0.9.10 beta 1 and beta 2 to bring Untethered jailbreak on iOS 5.0.1 firmware but both of these version were not stable and has many bugs inducing “launchctl” bug.To fix these bugs and issues iPhone dev team released Redsn0w 0.9.10b3.
According to change log:
“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)”.
