I've certainly had issues supporting iOS 4 vs 5/6. Most of the Android issues I run into have to do with WebViews behaving differently on different OEMs devices. Both forms of fragmentation can be a pain in the ass.

Probably games developers have it harder on Android, but for the average app it seems just about the same to me as a developer.

The key difference is if you cut out iOS 4 only users you're eliminating at most 2-3% of your market. If you were to try and do the same thing with Android and require ICS or higher you would be blocking off 50%+ of your market.

There is little expectation of iOS 4 support at this point, because users who purchased an iPhone in the last 4 years don't have to use it. The same is hardly true for Gingerbread. Most of the phones that shipped with that half-baked OS will have it until they're retired into a drawer somewhere.
