The Wall Street Journal recently reported their conversation with Verizon Wireless COO and soon-to-be CEO, Lowell McAdam, regarding the iPhone 4 data plan:

“I’m not going to shoot myself in the foot,” he said. Not offering an unlimited plan would put up a barrier for customers who might otherwise switch from AT&T, he said. The country’s No. 2 carrier still has millions of subscribers grandfathered into unlimited plans they signed up for before AT&T switched to tiered pricing last summer.

But you’d better act fast. Speaking later Tuesday morning, Mr. McAdam said the iPhone unlimited plan will be a temporary offer and that the carrier will follow AT&T’s move to tiered pricing in the not too distant future.

Asthe iPhone 4′s data plan pricing is now confirmed, TechGeec will have full coverage of Verizon’s iPhone which will be released February 10.
