The iPhone Dev-Team has released a bundle to the new TV 4.3 (4.22) build 8F305 firmware.
released a minor update to for AppleTV2G (the IPSW name still says 4.3, but the build version changed from 8F202 to 8F305). @i0n1c was once again able to quickly port his original 4.3.1 untether (the exploit that wouldn’t die!) to this version.
If you do feel like updating to the “new” 4.3, you’ll need to drop this bundle into the correct folder in PwnageTool.app. If you don’t know how to do that, there are lots of tutorials on the web, and we’d be glad to help in the comments below.
You can find instructions on how to add a bundle to PwnageTool here.
You can download the bundle here. Then follow the same steps as this tutorial.
