I stumble into this feature by accident. Very cool feature.
Good to know. I'm still waiting on my Iphone but have already been doing some app searching and buying from Itunes. I was getting worried that I would fill up the phone with apps. I guess I haven't even put a dent in it being able to hold 2000+ apps.
