Edit: I'm a m0r0n. I only have 23 months here. I guess I still have to count March for 24 months. My contract did start Feb 28, 2012 tho.
My contract just ended March 6th. Here's all my data usage for my whole contract.
2012
02-28 to 03-27: 258 mb
03-28 to 05-06: 219 mb
05-07 to 06-06: 473 mb
06-07 to 07-06: 1802 mb
07-07 to 08-06: 291 mb

10-07 to 11-06: 405 mb
11-07 to 12-06: 002 mb*1
12-07 to 01-06: 116 mb
2013
01-07 to 02-06: 157 mb
02-07 to 03-06: 006 mb
03-07 to 04-06: 006 mb*2

09-07 to 10-06: 901 mb*5
10-07 to 11-06: 634 mb
12-07 to 01-06: 733 mb
2014
01-07 to 02-06: 471 mb
02-07 to 03-06: 249 mb
Average usage for 24 months:
With the 1802 mb usage: 379mb
Without the 1802 mb usage (using 317 as an average): 317mb
I haven't decided what I want to do yet but I see they have the $130 plan for two phones. I have to call them and see how much it'll be with taxes and all that crap.
I will forever stand by my data usage that I did not use 1802mb of data in 30 days. It's just impossible. I still think ATT tried to pull a fast one on me and I caught them.
In reference to a post above that some say ATT can see our phones and others say they can't. When I started this whole fiasco back in July of 2012, while on the phone with either ATT or Apple, THEY KNEW HOW MUCH BATTERY I HAD LEFT so they MOST DEFINITELY CAN SEE into our phones. I would like to think they asked me first and I'm sure they did.
So they most definitely have the ability and sure they ask when they have you on the phone or in a store but the real question is; do they look when they DON'T ask you? I say yes.
