Mark it, Dude. The AT&T this morning announced that the Motorola Atrix HD is getting an update to Android 4.1 Jelly Bean starting today. That means you get cool things like Google Now, that Project Butter smoothness, plus all the other bells and whistles AT&T and Motorola have added in.
You can get the update now by going to Settings>About Phone>Software updates. And we suggest you do.
