Well, I rooted my Moto Droid 1. It was simple, no problems with it whatsoever. I used SPRecovery, installed (or flashed if that's the correct verbiage) the update.zip file, ran it and done. I've created a nandroid backup. I'm using FRG22D, I haven't installed any theme's or ROM's, but I'd like to. My question? Well I've read the post "So you've rooted, now what..", and I'm not looking to overclock. I want to install a Rom, or theme, or both. I'm interested in the Ultimate Droid Rom, but when I've read through....it mentions you must clear cache and wipe the data. Wipe the Data? Is this suggesting that I basically remove everything from the phone? If I do this what will I be losing? Will I have to do this for EVERY ROM? Also to install a theme, do I have to first install a rom? For example, 928 black glass, does that require a ROM be installed? Any help here would be appreciated.
