so, I tried to purchase Numbers in the AppStore...notification came up that I needed iOS 7, which I figured would...offered me to upgrade (no thanks...staying on 6 as long as possible) but did not offer to let me download a legacy version, which I thought was the policy now...is this only for third party apps?...if so, I find that strange, because I already have Pages and GarageBand, and just out of curiousity, I tried to upgrade them, and it told me I needed iOS 7 for this version, but it offered to let me download the latest compatible version, which is weird because I was upgrading, not purchasing...thoughts?
