Just reading between the lines on your post: don't think that iOS < 4.3 implies iOS 3. I think you'll find a much higher per centage of iOS 4.2.1 users. This the latest version supported by iPhone 3G.

egb more or less addressed this but I thought I'd make it explicit.

4.2.1 is indeed the largest piece (exactly 50%) of my users that are on iOS less than 4.3, with other versions sprinkled in. And as it happens, looking by device, 87% of my <4.3 users are on 3G devices.
