How do I remove the loop cell phone GPS tracking device someone installed in my cell phone?

My friend just had someone install some looping GPS tracking device without them knowing, they were able to see everything they were typing and calling and see exactly where they went by GPS. What is the program called and how do I uninstall it off her phone?|||you will have to go to something like "applications" then "manage applications" to delete it.





The program is called looped.
