Well for what it's worth....I only have the iphone 4s (thanks XXX for steering me in the iphone direction many many moons ago..). Not long after I got it in Dec 11 (after using the iphone 3) as part of my plan upgrade I downloaded Oz Runways.
I love it. It's a great app and I can't fault it at all. I use it alot and I would like to say that all upgrades will be greatfully received. I've been following this thread since it started and as a result will probably also end up taking the plunge and getting an ipad.
Geez, If I can't find my way around the sky now between Oz Runways, MyE6B, Navclock, Flightplan, Airnav and Commander Compass apps together with NAIPS, VTC, VNC, WAC, ERC (low of course!!!) charts, a Garmin 430 and 2 x mark 1 eyeballs then I better give the game away.......
