Hello I am just getting into hacking my droid and have a few questions. I am rooted and am running cyanogen.
1) What is the difference between a kernel and a rom?
2) Am I able to easily switch from rom A to rom B and then back to rom A without losing my settings on rom A? I am using clockwork and it makes it easy to back up and restore cyanogen, but can I do the same thing for other roms?
