Grandfathering my unlimited data plan

When I pre ordered my iphone 6 tonight the confirmation page showed that my unlimited data had been removed automatically. It didn't ask about changing my plan, it was a default that my unlimited plan since 2007 was automatically removed. WT*?

Same here!

I cannot pre-order the iPhone 6 w my current unlimited data plan:

There was a problem with your request.

We're sorry, but we are experiencing a temporary system error that prevents us from processing your upgrade online. For assistance, please call customer service at 1-888-867-4384.
(P1073)

This is ridiculous. I should be able to still have my unlimited data plan, and be grandfathered in when I order the iPhone 6.

I had the same thing happen to me (sliding in the removal of my unlimited data plan on the confirmation).  Guess it'll be a call to customer service in a few hours when they open up.  If anyone gets a resolution, please post it here!

They removed my messaging package and gave me a message about moving me to a Mobile Share Value plan once my new phone arrives. I chatted with ATT online and this is what I was told:

We'll see what happens in the morning, but I hope this helps others.

ATT web site did not offer me the older plans (like 3GB/mo) that I have to select for my son's phone to keep my unlimited data plan.  The web site offered only Family Share plans.

I bailed.

The Apple site, however, gave me all the choices.  I upgraded using Apple's site. (see below).

I will visit the store to set up my upgrade as I want to trade in my iPhone 5 (for $200).  That can be dome only at the stores, apparently.

samething happened to me...Ordered my iphone 6 at 3:20 am eastern received a confirmation sayong that my unlimited data plan was removed (the only reason why i stayed with at & t this long) i tried to call customer service right away but it was closed until 7 am. know ing that i wasnt going to sleep i put my alarm on for 6:50 am thinking id 1st call then go down to my local AT & T store.

called customer service at 7 got a representative at 7:15am. To my amazement after explaining my situation the lady understood where I was coming from and within 10 min i had a case and confirmation number texted to me and was assured that my unlmited plan would be returned!

Does anyone know what the "unlimited messaging enterprise plan" is?  how is it different from the "unlimited messaging" plan?

If our data plan says "unminited $30/mo" that is our grandfathered plan correct?  I am ordering from the Apple website.
