Cricket Wireless will start carrying the iPhone on June 22nd, the carrier has announced. The move will make it the first US carrier to offer the iPhone as a prepaid device, instead of on contract. An 8GB iPhone 4 will cost $400, while a 16GB iPhone 4S will be $500. A $55 monthly fee will get people unlimited voice, texting, and data, though data is throttled after reaching 2.3GB.
