In addition to the rest of the changes made to the Android Marketplace today, Google went on to introduce two giant changes to the way things are run in the Android Marketplace. One of them being the ability for each developer to set their own prices in each currency available. Before, this was automatic, the price being automatically converted for whichever currency the purchaser was using. The other fat change was that developers will now be able to make in-app sales. This is big news when you consider what’s going on with Kongregate on Android and the Apple App store stopping some book services from selling in-app.
