Hello! I just upgraded to a Bionic from the Original Moto Droid. I want to sell this phone, but I need to clear my SD Card. Even though I did a Hard Re-set on my phone, the SD card still has some old pictures and files. How do I clear it? From my research, I don't think I can just insert it in my computer and clear everything, or can I? will it still work on the phone? I've read that I could HAVE gone on the phone and done a "format", but I can't seem go back to settings cuz it wants to be activated. Help Please! TIA!!
