Apps are going to be cheap i think. Apple will obviously want some revenue from the apps market for the iPhone.. But I think that there will definitely be some developers who will give away for free such as maybe eBuddy or other MSN/Messenger developers.
With this in mind, I think that alot of free apps will probably have a change to get a "Pro" version for a small cost or some may have a "trial period" before you have to buy the full version through Apple.
