No, they are apart of your service books and are pushed to your device by your carrier. When you do a reset or resend your service books they will appear again. The best you can do is hide them, as long as you don't install the app, it's not doing anything...
Make a new folder (BB key) & move unused icons there, then put the folder to end of your last row & then hide it. It's completely out of the way from the rest of the icons.
Well if they are installed try uninstalling them, if you can't but they are embedded into the device use a program like CrackMem to remove the .COD file
