Verizon iPhone 4 Data Plans: $30/Month for Unlimited 3G & $20/Month for 2GB Mobile Hotspot

AT&T charges $25 per month for a 2GB per month iPhone data plan. Their iPad 3G plan has the same plan. However, for a brief shining moment (about a month), AT&T offered an unlimited 3G data plan for the iPad that some subscribers are still grandfathered into as long as they don’t interrupt the month-to-month plan. The Wall Street Journal reports that Verizon will offer a $30 per month unlimited data plan for an unspecified limited period.
