Apple has settled the class action lawsuit brought against the company by a group of parents who claimed that in-app purchasing took advantage of their children, who racked up large bills without knowing it. According to the lawsuit, children had made in-app purchases for as much as $300 without realizing what they were doing.
According to the terms of the settlement, most members of the lawsuit will receive a $5 credit to the iTunes Store. Those members of the lawsuit who incurred charges of more than $30 will get a credit or can apply for a full refund
In March 2011, Apple made it more difficult for kids to make in-app purchases, as such purchases now require a user to sign in to their account. (Via Apple Insider).
