I purchased a Droid X which had some crazy screen issues. It would scramble as if it were possessed. I returned it within my first 30 days of purchase and got a brand new Droid X with charger, 16gb sd card, battery, and battery cover. I don't know what this classifies as... a warranty replacement or insurance replacement and I don't know if its technically from Verizon or Asurion. My question is this though.. Can I keep the extra sd card and battery charger and just send back the phone with the old battery and battery cover?
