Free's new mobile division has become the fourth major carrier in France to offer the iPhone. The Iliad-owned group plans to carry the iPhone 4 and iPhone 4S on January 27 with one of the least expensive plans yet. At 20 euros ($25) a month for a 16GB iPhone 4S with unlimited voice and texts as well as 3GB of unfettered data before a cap, Apple's smartphones would cost roughly half as much or less to own as a phone with an equivalent plan.
