CancelUpdate is a tweak released during this evening in Cydia, and its main role is to allow us to cancel updates for applications from Cydia. The tweak displays an X next to the application being updated, and pressing it like this generates a cancellation of the download and installation. Unfortunately, canceling the process also automatically deletes the file downloaded up to that point on your terminal, so use it only in situations where you really don't want to download and are willing to start it again.
CancelUpdate it is available for free in the repo BigBoss of Cydia.
