Virginia-based nTelos will be the latest regional carrier to start selling the iPhone, AppleInsider reports.

The CDMA carrier will be undercutting other iPhone carriers across the board, offering each model for $50 less than AT&T, Sprint and Verizon, starting with the iPhone 4 for $49.99. nTelos' smartphone plan for iPhone offers unlimited voice, text and data for $99.99 per month.

Sales begin at 7 a.m. on April 20. nTelos is the second regional carrier to join the ranks of iPhone resellers. C-Spire Wireless, which covers the Deep South, started selling the iPhone in October.

nTelos covers Virginia, West Virginia, Maryland, Ohio, Kentucky and North Carolina.
