I apologize if this has been handled elsewhere, I tried searching but couldn't find anything that answered the question. I am a lucky one - I was having problems with my D1, took it into the store and received a D2 as a replacement via FedEx. The instructions on returning the old device indicate that "you MUST keep your original battery and battery cover for use with your new phone." I assume they mean they want me to send the new battery and battery cover back in? Thought I'd prefer to keep the new battery, in the end, I can't argue with that (they are the same battery). Along those lines, the D1 battery cover and the D2 battery cover are the same size, but different colors. I know i probably shouldn't complain as I'm getting a better device out of this, but I'd rather not have a 2-tone backing to my brand new phone! Has anyone else gone through the D1 to D2 upgrade? How did you handle these issues? Any help would be greatly appreciated!
