I had some great test runs last night with the GF on her iP4. No problems. 3G is a little choppy for sure, but over WiFi it was flawless. Only issue for me was that what I see on my little screen at bottom left (video of me) is at a much larger aspect than what she saw on her iP4. In other words, on my phone it looked like I had my whole face in the screen, but on her iPhone it was only showing my nose and eyes. Not a huge deal, just more of something to be aware of.
