Those of you who have been experiencing bugs after using JailbreakMe will be glad to find out that Comex made some fixes to the kernel patches for the userland jailbreak, and these fixes have been pushed as an “Essential Upgrade” in Cydia.
To get this update, simply launch Cydia and you should be prompted to upgrade. Make sure you do not run JailbreakMe again over your current jailbreak. Instead, let Cydia do the job for you…
A few people had been experiencing this issue where the Cydia icon would disappear. iPad owners who tried to use the Camera Connection Kit would also encounter issues because of JailbreakMe. This Cydia update will most likely fix that.
Thanks pukka for confirming this fixes the camera connection kit as well.
