Long story short, I am upgrading to the Razr Maxx before Big Red bangs me out of my unlimited plan, and I am going to sell my Droid 2 after I upgrade. It's rooted, so I will SBF it back to stock before I sell it, but how do I format the SD card before I sell it? Is there an app or an easy way to do it? I already backed up the contents of my SD card to my laptop. Thanks in advance for any help!
