Hey fam my name is Ben. I just got the new Droid x. Nice phone and lovin it. Only if I knew how to download themes.i
Themes for what exactly? I am not too familiar with the X being that I have the Droid1, but to fully theme the actual system of your phone you will have to root your device and then install a theme built for it. Like I said I don't know of any themes for the X because I don't read up on that stuff.
If you don't want to root and just want to change the look of your launcher I would suggest downloading LauncherPro (and pay for it) because it is very customizable and lets you change a lot of stuff. Other than that, i dono man.
