Saurik has announced that an update to the Corona Untethered Jailbreak has been released in Cydia.
The update fixes issues for iBooks and launchd and it's recommended that users who previously jailbroke their A4 devices install the Corona package from Cydia.
Corona (5.0.1 untether) 1.0-4 is now out: users of redsn0w or the older packages should install. This fixes both iBooks and launchd (again).
As many users don't realize that untethers only affects boot, I just released 1.0-5 of the Corona package, which forces a reboot on upgrade.
iPhone Dev Team have just released a new version of RedSn0w 0.9.10b4. It includes a fixes for iBooks and launchctl. As always, you can simply run the new redns0w over your current jailbreak, just make sure to uncheck Cydia. To fix iBooks and launchctl errors you can also simply install new version of Corona from Cydia.
