Apple has released iOS 4.1 for the 2nd-gen Apple TV and it is available for download.The new Apple TV which is built on Rental Model now completely depends on the cloud for streaming media content.So don’t as there is no local storage here.
Musclenerd has suggested to order Apple TV as soon as possible untill Apple fixes jailbreak exploit!
Those interested in *potential* AppleTV JBs, better to buy early! Remember iPhone3GS hardware was updated to fix JB hole.
