hi all. I have a droid(main line) : still far from eligible upgrade.(contract end 2011?) also have another 2 more line under my name and 2 are eligible upgrade. in this situaltion, Can I use another 2s upgrade to get a droidX? If so, my droid will be a free phone which I can sell this to someone? or should it goes to one of another line? 1. main line - my droid : can not upgrade for while. 2. my wife's : upgrade eligible - no data plan 3. my parents : upgrade eligible - no data plan Thanks.
