My husband is giving me his upgrade so I can get the GSIII. My own upgrade isn't due until November. The question is, if I use his upgrade to pre-order the phone, when I get it I can just activate it on my line without ever activating it on his, correct? He has a dumb phone with no data plan.
Also will this still put me in danger of the losing-grandfathered-unlimited-to-tiered-data-plan should that come to pass in the meantime?
