I just wanted to share, if you have been using the unofficial release of .9.2, make sure you back up your flight data in itunes before you upgrade to the official app.  It will over write the app when you install it.

If you connect your device to itunes, the DJI pilot app let's use save the data from the pilot app.  Then you can re-import this into the official app so you don't lose any flight data.

Happy flying!
