Google's Chromecast is a ridiculously cheap and easy way of getting content to your TV from your iPhone, but supported content is still extremely limited. One such service that has now been allowed through the gates is Pandora, with the switch flipped and now you're able to launch your Pandora stations on your TV from your iOS device.
The change seems to have been done server side, and all that's required is a copy of the latest version of Pandora – which you'll find at the handy download link below. It's a great addition to the Chromecast stable, though it is U.S. only. But then, so is the Chromecast itself, officially.
If you've already taken this for a test drive, let me know how you're finding it.
