Specific data plans for iPhone 4S (on AT&T)

[ckeck]

Anyone know what the difference is between the old data plans and the new plans specific to the iPhone 4S on AT&T?

The rep when activating said he has to switch my old Unlimited plan to the new Unlimited Plan "for" iPhone 4S. I also see this on the website. Since there was no issue with keeping the unlimited plan I wasn't sure what the change in feature code is for in the first place...

Anyone heard anything? Spoken to two AT&T reps who are clueless...

Basically want to make sure there is no disadvantage to moving to the "new" plan on my other line or keep my legacy even though they are both unlimited.

I haven't seen anything about it. I can't upgrade at the moment so I won't know for a few weeks if there is any difference.

Its a paper work and tracking issue from what I can tell. I too was switched from "Unlimited Smart Phone" to "Unlimited IPhone" and there is no difference as far as I know other then tracking.
