Can I delete factory-installed apps?

Is there a way to delete some of the Blackberry classic factory apps?

Press and hold an app until it starts to shake. If a trashcan appears beside it tap that to delete. If no trash can appears, it can't be deleted. (At least not easily and safely, if at all.)

Thanks...

For those that can't be deleted, I created a folder to place them in to cut down on the clutter.
