I was also hoping to find this. It didn't look like Paul ever ported the Desire camera app over to 2.2 for the nexus one, only the 2.1 version. I know someone else did but it sounded really involved and his port only worked with his rom. But, again, that was only on the nexus... I agree though, the desire z camera app is way better than the g2's version. It would be awesome to get it on a senseless rom.
