MostUSmodels of the Samsung Galaxy Note II have already been updated with Multi-Window -- a split-screen feature that allows users to view two apps at once -- but AT&T is the last of the four national powers that hasn't pushed the feature out to its customers. That will change tomorrow, as AT&T has confirmed to us in an email that it will roll out the new build over the air at some point during the day. We're happy that users won't have to rely on Samsung's proprietary Kies desktop software to update their devices, but minor downloads like this are typically facilitated OTA. There's no word on if the ROM will be pushed out in phases to minimalize the impact on AT&T's servers, but don't be terribly worried if you don't get notified right away.
