Apple is proving once again that if you don't play by its rules (which appear to change on a whim) then you don't get into the iOS app store. This time the company has reportedly rejected an e-reader app from Sony because the electronics maker was not selling e-books through Apple's in-app purchase mechanism, according to The New York Times . Apple takes a 30 percent cut of all in-app purchases made through its system.

It's not clear how Sony's application was selling content, but it appears Sony was trying to sell e-books using its own in-app purchase system. Apple reportedly told Sony, among other app developers, that Apple would no longer allow downloadable content to be sold within an iOS app unless it used Apple's in-app payment system. Apple also reportedly said the developers could no longer sell content outside an app and then allow users to download it to an iOS device later.
