I am about to root my droid x and install a rom. How can I make sure I get all my aplications back once I install a new rom? So I do not have to download each individualy. I would prefer a free way if there is one. Also any suggestions for a great fast and battery saving rom? Also I used to have a rooted droid 1 and used set cpu to underclock when sleepign to save battery. Can i still use this on the droid x once rooted to do the same?
