Hmm, if this “feature” is true, this will be one of the weak point for iPhone users. But this will be a great point for iPhone apps developer. As mention at theappleblog.com currently in OS 2.0, applications that you have purchased before, you will be able to download it again via the air, but for OS 3.0 you will be prompted either to buy it again or re-sync to your iphone via ITunes for free.
