AT&T announced on its official blog that the LG Escape will be receiving an update to Android 4.1, and that said update should be headed to devices starting today. The first release of Jelly Bean includes things like expandable rich notifications, Google Now, and possibly some Project Butter smoothness enhancements (all LG handsets I've seen have them, at least).
AT&T's DriveMode app is also included in the update, so there'll be another piece of carrier bloat (arguably of the less than useless variety) in your app drawer.
