Ok I downloaded the titanium backup and going thru and backup the ones i know are I want but what is DRM protected content storage 2.2, there are 2 enties for this should I back up them both or neither? and what is the wipe data tab used for and should I use it? why are they red and some are green? should I back up Astro? What happens to the things I dont backup but came on the phone in a reset, are they still there and do i wipe anything? what is DM command service 2.2 do i need to do these as well or just my contacts, gallery and messages and astro and let everything go back to day 1?
