I wonder how they are planning to do this because last I checked you can't transfer iPhone apps from one account to another without losing all app history. Last I checked, Apple's only solution is for you to delete the app and then republish it under the new account. This means you lose your rank and users who downloaded the app under the old account won't get updates unless they get it from the app store again. If there were a way to transfer apps while keeping history and ranking, I might consider selling some of mine too.
