Same situation here
I am in exactly the same position (have current $150 etf on one of two lines) and can't for the life of me understand why At&t doesn't offer the early upgrade equal to $250 or the amount of your etf at the time of the upgrade, whichever is less. To only keep it at a set amount of $250 encourages people with low etfs (i.e., long-term loyal customers) to switch to VZ, which is exactly what I intend to do. I would have actually considered staying with at&t and getting a microcell for my new house that has practically no coverage, because the coverage everywhere else is good, plus I like the simultaneous voice/text and the customer service is fine. But, they will be gaining a $150 etf while losing a 2-year contract on a family plan with 3 new iphone5s - their loss. Just can't understand the logic of it.
