9to5Mac is reporting that the latest betas of Apple TV iOS not only includes support for Bluetooth, but you can successfully pair a Bluetooth keyboard with an Apple TV for typing searches (and passwords).
Odd that this didn’t come to light earlier, but seems that there was a pretty significant bug introduced in iOS 6.0, which is fixed in iOS 6.0.1, that causes podcast episodes to download over and over again while you’re listening to the episode. Essentially, although you might have finished downloading the whole file in the first couple minutes, iOS would go back and re-download it all over again. And again. And again.
