Apple announced a new policy of locking in screenshot images submitted to the App Store alongside applications. The change is aimed at stopping app developers from using the bait-and-switch tactic of swapping out an approved screenshot with one suggesting a more popular app in order to boost downloads. "While this presumably means that scamming developers will no longer be able to game the App Store, it also hobbles legitimate developers trying to keep their app descriptions up to date," Steven Musil writes.
