How should I approach building a Universal iOS app that will include iOS 4 features, even though the iPad doesn't yet run iOS 4?

Question

I\'d like build a game for both the iPhone and iPad. As such, it would make sense to start this project from scratch as a universal app. However, iPhone and iPad currently run

This is a question that is all about managing risk. Risks include:

1. Apple doesn't release the expected "unified 4.1" OS within the timeframe you need
2. The OS is released on time for your needs, but one or both of GameCenter or iAds aren't included
3. GameCenter and/or iAds are included, but they don't match the exact API you were expecting
4. The APIs are what you expected, but they are buggy since it is the first version on the iPad
5. etc...

Only you can determine what level of each risk you're comfortable with, how likely you think each risk is, if you can mitigate each risk, and what the costs would be for any of these problems along the way.
