Boost Mobile is reportedly getting the iPhone 4S in September of this year, which is the first time in its five-year history that the popular smartphone will be available as a prepaid device. Cricket Wireless has announced it will begin carrying a prepaid iPhone 4S later this month, selling the 16 GB iPhone 4s for $499 and the 8 GB iPhone 4 for $399. Both phones will be available with the carrier’s $55 per month talk, text and Internet plan. Boost Mobile hasn’t confirmed the rumors yet, but according to a “trusted source” of TechnoBuffalo, the company will get it later this year, with a deal that will be similar to that of Cricket Wireless. Apple is obviously trying to reach untapped markets and provide some fierce competition to its competitors (like other Androids that have been made into prepaid devices).
