Samsung and AT&T are pushing a small update to the Galaxy Note II that includes Samsung’s Multi-Window feature of TouchWiz. If you haven’t seen it before, it basically allows you to quickly pull open a small side tab and switch between any applications… or run two apps at the same time side-by-side.

You can surf the web, for example, and quickly jump to your text messages, and then jump to maps, and then jump back to the web, all in a matter of seconds. Or you can have your notepad open on one half of the phone’s screen and maps open on the other half. The feature was initially available on the international Galaxy Note II but, for whatever reason, was omitted when AT&T first launched the phone.

The update is 180MB and should be available over-the-air now. Let us know what you think.
