i have some simple questions about starting rockbox-can i get some quick responses?

[thewindsurfguy]

1. Is Rockbox available for the e200R?
2. If you want to take off Rockbox and go back to the original firmware, is it possible?
3. In the process of installing Rockbox, will my data be lost?
4. Is there a way to make the Rockbox menu theme look a bit less...primative? I saw something about "Rockbox Themes" are those similar to H3MOD themes for the e200? And are Rockbox Themes available for the e200R?

Thanks guys, and if you can please give me a quick response in the interest of time I currently have, that would be great. Thanks again! (and yes I have an e200R/Rhapsody player, )
