During this day, saurik released in Cydia an update for the MobileSubstrate plugin, with the help of which a good part of the tweaks and applications available in its platform are built. The update brings users full compatibility with Apple's new iOS 5.0.1, but it represents a basis for future updates. Many tweak developers were waiting for this update to update their creations available in Cydia and now they can do so without problems.
If you have MobileSubstrate installed, I recommend you to be cautious because some people who installed the update say that all the packages affected by it have been deleted.
