Currently the team is working on overall 4.3.x jailbreak issues and getting Cydia ready for the release. I0n1c's untether has been tested and described as 'solid'.
The upcoming releases of RedSn0w and PwnageTool will support the Apple TV 2 but will not support the iPad 2. Musclenerd notes that they are waiting to find a legal method of distributing comex's 4.3 jailbreak for the iPad 2 before they make it public.
