Will the AT&T update for the HTC One x work on a T-mobile HTC One x?

Hey everyone! So...I was wondering if anyone knows the answer to this question. I'm not really sure why T-mobile is dragging their feet on the Android 4.2 update for the HTC One x but as many of you may know, AT&T already has it out on the official HTC website. Is it even even possible to install the update without messing up the phone?

Thanks!
