HTC has been quite quick to bring out the Android 4.3 update. International units began receiving the upgrade earlier this week, and now the Taiwanese company has announced that the rollout for the developer edition of the device has started. It makes sense that these versions of the device are seeing it so early, as HTC doesn't have to deal with annoyingly lengthy carrier approval processes.
