i wonder if an epic camera.apk will work. i know you would lose 8mp mode but there are some nice features in the sgs that we are missing. not sure if the epic has all of them but it is the only one that has a flash and 2 cameras.
better yet i wonder if the sgs2 camera will port into 2.2.1, it said cant parse package when i tried, that seems to be it being a gingerbread app, i have seen that message before with gb apps. i know it works on the galaxy s if you have gingerbread. i just wish i knew how to make it install in 2.2.1
