My first Android "app" (actually, a runtime for HTML5 apps call Blossom[1]) only will run on ICS because its requires hardware-accelerated graphics and surfaces.
On iOS, I could support all the way back to the original iPhone, but I'm actually requiring iOS 5 (that includes all three iPad generations, and the iPhone 3GS, 4, and 4S) mainly so I can use ARC and because people in the iOS ecosystem update so fast anyway.
