compatibility

I'm in the early stages of an iPhone app and I have a question. I did some searching but did not find what I was looking for.

There are features in iPhone OS4 that I would like to take advantage of, but I would like for my app to also run on 3.X.

It looks like I want to develop against the 4.0 SDK and do the following:

Create a "weak link" to any new (4.0) frameworks
Call respondsToSelector: for any new method in an existing framework or any method in a new framework before making that call

Am I close? What's recommended?

Pointers to similar questions welcome.
