Is there any reason to build for LCD?
If I can do everything I need to with iPhone SDK 3.0, is there any reason to build for 3.1.2? 3.0 still runs on 3.1.2 devices but not the other way around righ开发者_开发问答t?
Correct. The earliest version that provides the APIs you need will offer the most support to users. Some people just don't like to mess with things, like they're afraid they will break something. Those people usually don't upgrade unless they're forced.
