I got a notice from Apple this week that all apps need to be built using
XCode 5 and optimized for iOS7. I use FlashBuilder 4.7 and I've got the
flex 4.6 SDK that came with it but I've upgraded the AIR SDK to 3.9 and
compiled against that. Will that be enough to satisfy this requirement or
will an upgraded version of FlashBuilder or compiler be needed?
