The earpiece on my Droid had developed an annoying buzz when anyone talked (annoyingly just outside of the 30 days). I just received my barebones (no battery, accessories, battery cover, etc) replacement, but what it does come with is an SD card. Am I excepted to ship this new card back with my old phone? Verizon's pamphlet says to keep all my accessories, including memory cards. Has anyone else received an extra card, and what have you done with it?
