New version of iOs 5.0.1 untethered jailbreak utility was released – RedSn0w 0.9.10b3. New version fixes issues with launchctl and MobileSubstrate that many users experienced. The same fixes were integrated to Corona package.
So if you had any problems with Cydia apps or faced errors while jailbreaking – update Corona or rerun RedSn0w (remember to de-select the “Install Cydia” option if it’s already installed).
You can download RedSn0w 0.9.10b3
