CyDelete is a very old tweak for iDevices that allows you to delete installed applications from Cydia. Normally, applications installed through Cydia can only be deleted by manually uninstalling the application, but CyDelete greatly simplifies things by giving us the opportunity to delete all applications directly from SpringBoard, just like in the case of applications installed from the App Store. Recently the tweak was updated by its developer and the new version released in Cydia brings compatibility with the new iOS 5.
CyDelete is available for free in Cydia in the BigBoss repo.
