Is anyone working on a tweak to enable AirPlay Mirroring on non-A5 iDevices? Now that the 4S and the iPad 2 have been jailbroken, can't this functionality be brought to our older devices with a Cydia tweak? I suspect there would be some demand for this but despite scouring the Internet, no one seems to be seriously working on this. Not a hacker myself, I would have no idea how to do it and I'd really like to use AirPlay mirroring with my jailbroken iPod touch 4g. Help!
