It appears us 2G users/early adopters can upgrade to iPhone 4 and keep unlimited data.
However, as I read AT&Ts iPhone 4 FAQ is states:
Existing AT&T smartphone customers upgrading to iPhone 4 or iPhone 3GS are not required to switch to a new plan, but can choose to do so. iPhone 4, iPhone 3GS and iPhone 3G customers can add tethering to AT&T DataPro for an additional $20 per month.

Doest that mean I can keep my current data plan at $19.99 with 200 txts?
