Samsung Galaxy S III getting multiwindow update

The Galaxy S III was already touting Android 4.1.2 Jelly Bean but it got a small incremental update to give it functionality that was exclusive to the Galaxy Note II and Galaxy S4 and that's the Multiwindow support. So far the update has been pushed out to the Rogers, Bell, TELUS, Koodo, Fido and MTS (as well as Virgin we assume) versions of the S III and will hopefully also hit the AWS variants on WIND, Mobilicity and Videotron.

The update reportedly also improves download speeds on HSPA+, alerts users when VoIP applications could interfere with E911 calls and also include the Group play functionality found on the S4.
