In this talk, I discussed all of the things that are important for making a successful iPhone application. A lot of this information I pulled from my experience working on Bible (an iPhone app used by over 12 million people world wide) and various client applications with Tasteful Works.
I mentioned Remember the Milk's unique model for making money, as well as Pinch Media's AppStore Secrets blog post regarding how much to charge for iPhone applications and various other things.
