More details are now public about the deal Apple reached in June to settle claims that it engaged in price-fixing in the e-book market. That settlement was approved by a federal judge on Friday. It's an unusual one, in which Apple essentially bets the outcome in its class-action lawsuit on the outcome of another case. In 2011, Apple got sued in a class-action case, where a class of e-book buying consumers was ultimately joined by attorneys general of various states.
