<PRE> means that wifi is pre-configured to automatically connect. So anytime that network is found, the iFly will connect to it.
The only other thing you need to do to setup your connection to FreeFlight (or any other ADSB device) is to tell the iFly software what kind of device it should be listening for. Do this by touching Menu / About / Connected Devices / WiFi Device, and select it from the list.
