Then, as far as Android 2.2, there are a lot of different versions out there.
Just look in the Development area for the S7 and you will find plenty of 2.2 installations.
Don't be shy with asking questions, but you may try to search first.
I know I had to look through a little before I found what I wanted.
If you can't find it, ask. It's out there, and the people here are very helpful.
Good Luck, and I hope you enjoy your S7 as much as I enjoy mine!
