Yesterday I rooted my DX using z4root and backed it up with titanium. I didn't do boostrap because I don't want to change ROMs (that part kinda scares me, I'm afraid of screwing up my phone...I know I already rooted and that sounds dumb). I saw a really cool theme that I would love to have but it has it listed for liberty (I know thats a ROM). Do I have to change ROMs to do themes or is there a way to do a theme with just what I've done to my phone so far?
