Initially, the response will likely be no. But as the defections en masse begin when iP4 is open for general sale at VZW stores, ATT will be forced to reconsider. They cannot lose too many subscribers.
I asked about unlimited for a second line in a store last week and was told not going to happen because most consumers don't use that much data and that the pricing was fair. Nice for them to make that call for me on what's fair and how much data they think I should use.
I really was going to open up another line for my biz, but it's not going to work if I can't get unlimited everything for a reasonable price.
