Greenpois0n has just been updated to RC6. This is the first version of Greenpois0n to be untethered on a second generation Apple TV. Pervious versions of Greenpois0n have been untethered on other iOS devices, but this is the first one that doesnít require you to have it connected to computer when you want to restart the device. You can safely put your Apple TV to sleep and know itíll still be jailbroken when you turn it on the next day.
A nice addition to this version of Greenpois0n is that it loads NitoTV onto your Apple TV during the installation process. You no longer have to use the Terminal window to get it loaded onto your Apple TV anymore. Currently, this is about the only addition you can make to an Apple TV, at least until Apple decides to open an App Store for the Apple TV. Steve Jobs has hinted at the possibility of opening an App Store but only if and when the time is right.
As always, proceed with caution when installing jailbreaks such as this. The current version of Greenpois0n RC6 is still considered to be in beta. There have been a few reports of people running into issues with Wi-Fi and booting. As Apple continues to develop the device, jailbreaks like Greenpois0n will mature and give us more choices as to how we use our Apple TVs. I canít wait to get more content streaming to that shinny little hockey puck sitting next to my TV.
