Verizon offering unlimited data plan for limited time

Verizon will now offer those who purchase an iPhone a $30 unlimited data plan.

Verizon COO Lowell McAdam explained that not offering an unlimited plan would prevent customers who might otherwise switch from AT&T from doing so. Anticipation that Verizon would soon offer the iPhone kept sales down in the fourth quarter of 2010, he said.

McAdam also said the iPhone unlimited plan would be temporary, and that the carrier would follow AT&T’s move to tiered pricing in the future.
