In-App purchasing for free apps.

It is now possible to use In-App Purchase within free apps to sell content, subscriptions, and digital services on the iPhone.

This is great news as it means we can simplify development by creating a single version of an iPhone app that uses In App Purchase to unlock additional functionality, eliminating the need to create Lite versions of apps.

Using In-App Purchase in apps can also help combat some of the problems of software piracy by allowing verification of In App Purchases.

Some good Q&A…
