Thanks!

Well, there are lots of differences between iPhone OS 2.x and 3.0, but it's not like you have to learn a new coding language. It's more like having a whole bunch of new options, like the inApp purchasements or sending emails with attachments directly from your app, etc...
Check out the following link for major iPhone OS 3.0 features:

If you build against 2.x, your app will certainly run on iPhone OS 3.0, but if you compile against 3.0, it won't run on 2.x.
