Still waiting, but am using my wife's 38mm Sport WSB, which is taking the edge of the wait. Can't wait to get mine though with the larger screen.
IF anyone is interested, I couldn't get her iPhone 5 to pair with the watch (via the camera or manually) and was on the phone with support for 90 minutes. My iPhone 6, paired immediately.
However, her phone is pretty bashed up, the screen has been replaced on numerous occasions and they asked me to reset the phone as it was showing up with errors on their diagnostic tool.
