A new webpage has gone live to explain the details of the Apple In-App purchase settlement.
To be eligible for an iTunes Store Credit, or in some cases, a cash refund, you must: (a) have paid for Qualified Game Currency Charges that a minor charged to your iTunes account without your knowledge or permission; (b) not have knowingly entered your iTunes password to authorize any such purchases or given your password to the minor to make any such purchases; and (c) not have received a refund from Apple for those charges.
