Bear with me, as I've never moved from one custom ROM to another. I am currently running a 2.1 BB ROM and would like to move to the new 2.2 version.
First off, do I need to load 2.2 before moving to the new ROM or will that happen automatically when I install the new ROM?
Secondly, will I lose my data (text messages, call log, etc..) when I move to the new ROM or will it be retained?
I tried searching for these answers and couldn't seem to come up with the right combination of search terms to find the answers.
