I am always amazed at the effort and skill that hackers show whenever there is a new update.
The most recent update on the firecore site states that they already have a tethered jailbreak and are working out other kinks.
This likely means that a full working jailbreak will arrive in the next month or so.
I went ahead and accepted the OTA update to my Apple TV2 when it came out (it is iOS 4.4 on the ATV2, the numbers are still not in sync with the software numbers for Apple phones and tablets).
Wanted to see all the new features. I must say, they were impressive. I liked the Wall Street Journal feed, as well as the the new hockey Feed.
Mirroring from the iPad and other iOS devices will be great for gaming and sharing video and pictures with the family and I really liked the new photo streaming and screensaver options.
All that being said, I have really come to rely on the jailbreak and my XBMC for a great deal of our video entertainment since cutting our cable.
So after playing with the new iOS for a few hours, I re-jailbroke the ATV. This required reverting back to iOS 4.3.
I look forward to having the best of the new Apple software in conjuntion with my hacked add-ons. I am willing to wait a little longer.
