[Q] AT&T Device Management Notifications topic

Hey folks,

Long time no talk. I have a rooted Galaxy S3 running 4.3 on AT&T. And lately I can't seem to stop these very annoying push notifications for "AT&T Software updates". As my phone is rooted (so I can use my unlimited data plan for tethering), I can't do the upgrade.

How do I kill these notifications? There are driving me nuts. :confused:

Thanks.
