Wanted to try a little more Airspace this (long) weekend and learned 2 things, first is that our mobile network at site is really bad...
Second is that I've tried to use Airspace with the (free) app on my iPhone and worked as a charm. Then I've tried also with the Hangar paid app and worked as well. So the iOS beta had nothing to do with it.
One word of advice when using the free app, give your device a different name then the normal app. Because the leading device will recognize both... And correct calibration is essential for not crashing
