How to create iOS app with multiple sdk versions?

My app is basically built in iOS sdk 4, and it is nearly completed.

I am looking to use one or two new features in sdk 5, should I need to create or re-factor the current app in sdk 5 ?

Could I submit an app with multiple sdk versions to Apple ? (e.g. one is built & deployed in sdk4, and the other is built & deployed in sdk5) ?

Any smart ways to tackle the above problem ?

You us the 5.0 SDK and set the deployment target to 4.x. You will need to check if classes and selectors are available using NSClassFromString and -respondsToSelector:.

Have a look at 'Session 130 - Future Proofing your Application' from WWDC 2010.
