How did they override the $40 to $25 if your still in contract? Im in the same position and they told me i cant do it, same plan you had 450 mins, 2gb data, unlimited text.
Basically, when you sign a new 2 year contract AFTER 3/8/2014, the +25 is going to be +40. Unless you use AT&T Next program in which the device fee stays at +25... or you bring your own device and paid full price.

See "Step 2" section
"*** Available with AT&T NextSM or if you purchase your smartphones at full retail price. You’re also eligible if you’re out of annual contract or bring your own device. " (Re: +25/mo smartphone adder).
"**** For plans 10GB or higher, AT&T customers with smartphones on 2-yr agreements as of 2/1/14 are eligible for the $15/mo. rate. For plans 2GB to 6GB, AT&T customers with smartphones on 2-yr agreements as of 3/8/14 are eligible for the $25/mo. rate. If upgrading, must comply with then-current req's to keep discounted smartphone rate." (RE: +40/mo smartphone adder)
