Glitch affected some apps for jailbroken devices
The unofficial iPhone Dev Team has posted a minor update of redsn0w, its popular jailbreaking utility for iOS devices. The v0.9.10b2 update incorporates a launchctl-related fix on top of the base v0.9.10 release, which was published earlier this week as one of the first tools allowing untethered jailbreaks for iOS 5.0.1. Mac and Windows distributions are available.
The glitch was reportedly causing authentication problems, in turn impacting apps such as IntelliScreen. The Dev Team notes that applying the fix involves simply running redsn0w again, making sure to power down the iOS device beforehand, and deselect the "Install Cydia" option.
