Okay, so I was planning on adding a new line to my Premier account (it's on a family plan), and then do an upgrade swap in-store, where I would set up a new line, buy the 3G S, and switch it over to my main line all at the same time. Could I do this? I know that would leave me with an extra line that wouldn't be in use, but I was just going to let it charge me the $10 a month for that line until I could eventually cancel it. So, can I do all this?
