iPhone Dev Team has released Redsnow 0.9.10b2 which fixes “Launchctl” error prevalent in Redsn0w 0.9.10b1 . This version will further stabilize the iOS 5.0.1 untethered jailbreak on iPhone 4 .
Launchctl is an application which assist Redsnow jailbreak tool to load and unload daemons. This is the reason why some cydia apps that depend on these daemons did not work well with the iOS 5.0.1 untethered jailbreak as complained by many jailbreakers.
The jailbreak tool has been updated but the method remains same. If you are already jailbroken using Redsn0w 0.9.10b1 , just run this jailbreak over your existing jailbroken device and deselect “Install Cydia” option . Alternatively you can download and install Corona jailbreak tweak from Cydia which will also resolve the “Launchctl” issue . download-redsn0w-0-9-10b2
