How to create single binary which will be compatible for both 2.2.1 and 3.0 versions

Hi All,

I have created an iPhone application using 2.2.1 SDK. But now I am able to build using 3.0 SDK. my question is it possible to create a single binary of the application which will be compatible for both 2.2.1 and 3.0 OS versions.

If possible how can I create it?

I am looking forward for your reply..

Regards,

Creating a binary using 2.2.1 as the active SDK should also work on iPhone OS 3.0, unless you have implemented 3.0 features, such as "in-game" purchases.

As an example, my first application (Buckets), required no modifications when OS 3.0 came out, as the 2.2.1 build also worked on OS 3.0.
