I have a first generation iPad that cannot upgrade to iOS 7 and won't let me install the most recent ersion of Skritter (2.4). I've heard that Skritter 2.2 should work on iPads running iOS 5.1, and I understand that Apple won't let you upload older versions to the iTunes store, but is there a way I could get a copy of an earlier version of Skritter that would work on iOS 5.1? Thanks!
