I also recommend getting Notepad++

All right, first of all, go into your SSH file view, and then go to the root of all the files.
Now, go to system, then library. Then Open "CoreServices". After you open CoreServices, your going to want to open "SpringBoard.app". Then open "English.iporj". & then finally, copy the file "SpringBoard.strings", and put it into a place where you can easily get access to it. Now, right click and open with Notepad++. Scroll down and find "AWAY_LOCK_LABEL" and replace "slide to unlock" with what ever your want. After your done making the changes, your going to have to respring your iDevice. Wallah! Your done.
