I`ve use the Ipad 1 with a plug in device called BadElf.
It is superb, picking up and holding signal far better and more quickly than my hard wired Bendix King.
Flew from Fife to Stansted and back with absolutely no signal drop out or any other problem using Skydemon.
Was also able to simply file a flight plan during the Olympics to allowing entry to the restricted zone in force at the time.
Would throughly recommend it
