Trade-in a single line on a multi-line account?
One of the terms of the AT&T Trade In Program states "Activate eligible postpaid unlimited wireless service (min. $75/mo. for new unlimited customers before discounts)." My account has 7 unlimited lines which each cost $30. Would a single line be ineligible for a trade in since it's less than $75? Or does the $75 minimum refer to the account as a whole? (I'm specifically interested in the $1,000 bill credit trade in offer.)
