According to the support website PSN update is live and 360 is expected later tonight...
Update -- 2:00 PM ET 10/4/13:
The latest title update for GTA Online is live for PlayStation 3. We're working to have this up for Xbox 360 as soon as possible today.
Do any of the PS3 players notice a difference?
