With Verizon en route to sell the iPhone come February 10th, this is where competition becomes interesting.

Per the Wall Street Journal, Verizon COO Lowell McAdam confirmed that it will offer its US$30 unlimited data plan during the launch of the iPhone but stated the plan will only be available for a limited time. McAdam did not specify a cutoff date for offering the plan, but he reiterated statements the company made in June 2010 that Verizon will soon follow AT&T’s lead and drop unlimited data plans altogether in favor of a tiered pricing model.

Even though Verizon plans to eventually drop its unlimited data plans, this comes as good news, as iPhone owners are known to gobble much more data than users of competing devices.
