Bored with FaceTime calls? Not the FaceTime its self, but want to spice up what its called? Maybe some HammerTime? Youll need to SSH in (I like YummyFTP) or use something like PhoneView and a text editor. Just edit these files:

/System/Library/Frameworks/AddressBookUI.framework/English.lproj/vc~AB.strings
/System/Library/PrivateFrameworks/Conference.framework/English.lproj/vc~Conference.strings
/private/var/stash/Applications/Preferences.app/English.lproj/vc~Restrictions.strings

And change out anything that says FaceTime to what ever you want to call it.

You can even call it FSMTime..you get my drift.

Dont forget to back up those stock files, incase something goes wrong.
