Not that the App Store now has stopped because of a report by Flurry showed that during the Christmas season a lot of apps are sold. This is due to the large number of people who have an iPhone, iPod touch or iPhone and get immediate gift is filled with interesting apps. At Apple were 12 times more active units than on a normal day.
Price changes that developers have made before closing are now implemented. So beware, if you thought a little Christmas a bargain to be met. The easiest way is to update apps using iTunes on the desktop , especially if you have many.
