Users around the world are noticing that they're no longer able to re-download older iPhone and iPad apps and games that their developers have removed from sale on the App Store.
The abnormal behavior flies in the face of Apple's policy of allowing people who bought apps from the App Store to re-download them to other devices through the App Store's Purchased tab.
As a result, questions arose as to whether this pointed toward a big problem in the App Store. Sadly, as PocketGamer points out, this is definitely a new Apple policy meaning you now have to back up your purchased mobile apps in iTunes to keep them forever.
