Yes there sure are you can there are plenty of options for you. You can remove them completely from your BB... Search for "how to increase file free memory" by Stoner. You can also wipe your BB, essentially restoring it to the factory settings (i.e. The way it was when you pulled it out of the box) by going to options>security I believe

You can use desktop manager to remove it. Application launcher will do the job. After you remove it the BB will reboot. It will take a little time to come back up. Just let it do its thing and it should come back to the default theme
