No contract required with Virgin's iPhone 4 (pictures)
Though it doesn't look any different from all the other carriers, Virgin's iPhone 4 doesn't lock users down with a two-year contract. But this comes at a hefty price.
Virgin's iPhone 4 is commitment-free
Although $550 is a steep price, Apple's iPhone 4 for Virgin Mobile doesn't require a two-year carrier contract. In addition, on top of the carrier's $55 monthly unlimited talk and data plan, it also has mobile hot-spot features for an extra $15 a month.
