I have a iPad 1 and iPad 3 and I just got a iPad Air. I want to run the Nikon Wireless Mobile Utility On the Ipad 1 and 3 it shows in the apple store but it requires IOS 6+ so I got a ipad air but it does not show in the apple store on the Air? Can someone tell me why this is? When I look at the specs on the ipad 3 it says it works on the ipad and needs ios 6 or later and it supports ios 7. Does this mean the ipad air is not backwards compatible with other ipads?
