I have Glasklart HD theme and just enabled the included 'Glasklart HD No Unlock text' and it worked fine. So I am assuming that nothing has changed from 4.1 or else it should not have worked for me (I have not actually updated that theme in ages as I just keep manually adding icons as I need them instead, so the files I am using right now for it, are still the same ones from 4.1)

I just went into the springboard.app and changed the string in there like i've always done and it worked fine also.
Found out my problem, im using AndroidLockXT. If i don't then it the slide to unlock text will only show up. Is there anyway to use AndroidLockXT as well as No Slide To Unlock?
