Associated Press is reporting that AT&T is allowing some customers who previously had unlimited data plans for iPhone to change back to unlimited in order to prevent their switching to the Verizon iPhone.

Jose Argumedo, of Brentwood, N.Y., says he and a friend were switched to an unlimited plan recently after they called AT&T's customer service. Both have iPhone 4s, and previously had iPhones.

Verizon is offering unlimited data as a lure to get AT&T customers to switch over. AT&T wouldn't confirm any plan-matching was going on so if you call up and give it a try, let us know what happens!
