If you consider rotation, the iPhone currently has 4 resolutions and will soon have 6. There's also the expanded green status bar during calls, a red one during voice recording, and another color for background VoIP apps in 4.0 -- so it'll really be 12 resolutions. The real difference is that with iPOS, Apple doesn't expect developers to automatically handle new device resolutions, and no developer expects to not be informed of new resolutions. Android developers are expected to use fluid layouts, and don't expect to be able to keep up with the release of new and customized devices by a bevy of semi-incompetent manufacturers.
