Apple has agreed to settle a lawsuit filed by parents whose children had access to their iTunes passwords and racked up unauthorized charges -- sometimes in the hundreds of dollars -- by buying in-game currencies through in-app purchases. The company will issue $5 iTunes credits in most cases but may be obligated to provide full "refunds" (though it was not the company that collected the money) due to a loophole where an authorized purchase could be followed by an unauthorized one for several minutes afterward without re-asking for the password.
