Verizon CEO Lowell McAdam on Tuesday confirmed to The Wall Street Journal that Verizon Wireless will offer a $30 unlimited data plan for the iPhone 4. McAdam said that offering the iPhone with a capped data plan would create an unnecessary barrier for customers looking to switch from AT&T. “I’m not going to shoot myself in the foot,” he told the Journal. The move also gives Verizon Wireless an advantage among customers looking to make their first iPhone purchase. While existing iPhone users on AT&T’s network may be grandfathered into the carrier’s old unlimited data plan, new subscribers are forced to choose between two capped plans, the larger of which only provides 2GB of data for $25 per month. Set to launch on February 10th, Verizon Wireless bills the iPhone 4 as the device that millions of its subscribers have been waiting for.

UPDATE: McAdam later stated that the iPhone’s unlimited data plan will be a limited time offer, after which Verizon Wireless will move to capped data plans similar to the plans offered by AT&T.
