Ever since AT&T killed its prepaid plans for the iPhone, we've been waiting for another US carrier to step up, and now Cricket is ready to bring the prepaid love back to Apple's smartphone. Beginning on June 22nd, Cricket will sell the iPhone alongside a $55 month-to-month plan that brings unlimited voice, text, and data with it. No need for a contract. You can choose from a 16 GB iPhone 4S for $500 or an 8 GB iPhone 4 for $400, and that unlimited data actually tops out at 2.3 GB (which is actually a limit.) Still, this frees you from having to be stuck in a two-year contract.
