Apple has introduced a new Apple TV 3 device with the release of iOS 6.1 (5.2) for the ATV.
The device called AppleTV3,2 runs the same firmware build (10B144b) as the AppleTV3,1.
iH8Sn0w commented on the new build saying:
New Apple TV3,2 is powering a s5l8947x with a board config of "j33iap". Looks like a minor update of the Apple TV 3. I Wonder why though...
It's unclear if Apple has already begun selling this device in stores or if it will be released shortly.
