I have been telling people that ATT (like Sprint ending their 12 month upgrade premiere program) has ended their 12 month upgrade cycle.
ATT started doing this in March or April 2011.
The reason it hasn't been widely reported is because the vast majority of users eligible for 12 month upgrades had been holding off until the iPhone announcement.
Since iPhone 4S preorders began, I knew this type of complaining about 12 month upgrade cycles ending would began. People simply do not listen or believe what people post.
This has been clearly discussed over in Howard Forums's ATT section. Android users over on the android forums also reported not been eligible for 12 month upgrades after they upgraded to say an Atrix or Inspire. Even waiting 3-4 months after using their Atrix or Inspire upgrade, their upgrade cycle is now set to around 18-20 months.
Sorry people just have to learn the hard way when the masses start realizing ATT is no longer willing to upgrade their most valued ($$$) users ever 12 months for their primary line.
I believe Verizon ended their new every 2 year thing this past winter also. Sprint doesn't have 12 month upgrades after people use their last upgrade. And ATT just did the same.
Could they change the upgrade cycle in the future? Maybe. But for now, they are treating primary and secondary lines the same in terms of upgrade cycles instead of giving the primary line the special 12 month upgrade cycle if you meet certain monthly revenue projections.

Does anyone know when the early upgrade takes place?
A full upgrade is 20 months, but what about the early one?
It used to be as soon as less than 60 days. Now ATT requires 6 months before the partial upgrade. Keep in mind, once you use their partial upgrade, you cannot do ANY (full or partial upgrade) for the next 20-22 months.
So if you use a partial upgrade for iPhone 4S (5th generation) (say $449), when iPhone 6th generation comes out in 2012, ATT will force you to buy at no-committement price and no partial upgrade pricing will be available at that time.
I know that for a fact since I was stupid enough to do the partila iphone 3GS upgrade back in 2009 and realize I couldn't get another partial upgrade for the iPhone 4 in 2012 and had to wait till I was fully eligible in 02/2012.
