Hi, My friend is getting a buy-one-get-one-free deal with a Droid 3 or Droid X2, and it seems like while either of these phones are excellent, some duds have had battery life problems. I'm just wondering, if I get unlucky and end up with a phone like this, will I be able to take it into the Verizon store and exchange it within 30 days, as long as I have the box and maybe a receipt? Or does it need to be linked to my account? Also, related question: should I get the Droid X2 or the Droid 3? I've gotten the sense they're pretty comparable, except the Droid X2 might not be getting any more firmware updates? Thanks!!
