Apple made a small but significant change without announcing it onstage today at its World Wide Developers Conference in San Francisco: It is now accepting “approved virtual currency” apps into the App Store. That could turn out to be great news for Bitcoin fans, including Coinbase and other cryptocurrency wallets that haven’t yet been able to grab some iPhone screen space. From the App Store’s newly revised guidelines: “Apps may facilitate transmission of approved virtual currencies provided that they do so in compliance with all state and federal laws for the territories in which the app functions.”
