I know there have been a lot of problems with people forgetting their code, and not having ssh so they can't get rid of it. I have found a simple way to help. Go to cydia, search activator, install, exit, go to settings, activator, everywhere (or anywhere). There is a list of functions to do things. Pick a function involving the buttons (home, volume or sleep) and from the list of options that appear choose unlock device. This automatically skips slide to unlock, and since android lock is really just a custom slide to unlock it bypassesthe lock, so you can uninstall app.
