Adds on free apps
I think this feature will free app developers some money as 60%(Developer) – 40%(Apple) model adds are hosted by Apple and served.
So Finally Apple read your earlier blogs and decided to come up with the Multitasking 🙂 I think 4.0 version should also be portable or rolled out on IPADs later on.
