Can i use the new AirPlay features by just updating iPhone/iPad to 4.3 or do I need to update the AppleTV as well before this will work?
Need the ATV update. It's out there, comes with a BUNCH of new stuff, plus the Airplay update. Some people aren't seeing it yet so you may have to be patient and check back. I haven't tried mine yet. I guess I'll go do that.
