ENGADGET: Apple aware of corrupt apps issue, working on a fix (Update: Fixed!)
In an open letter last February, Apple Chief Executive Steve Jobs argued that licensing its FairPlay technology to others would limit its ability to keep its DRM scheme secure.
Mr Jobs grumbled that he had been forced to introduce FairPlay by the majors, which would not otherwise have sold their music through Apple's iTunes, the leading online music store.
Digital rights management schemes, such as Apple's FairPlay technology, limit how many times users can copy their music and what devices they can play them on, ostensibly protecting music from piracy.
