does costco allow you to use the upgrade status of another line or can you only upgrade the line eligible? I was trying letstalk and they only allow you to get the phone to the line eligible (well, at least the phone has to stay with that line for 6 months). I wanted to see if it was worth the effort going back and forth to costco if I can't even use another line's upgrade anyways. So in this case I'm only stuck with getting it thru vzw.
You can transfer an upgrade from another line. The guy behind me in line (who was also buying a Bionic) did just that. The Costco employee said it would be no problem, and they were already activating his phone by the time I left, so it seems to have been fine.
