An eleven-year-old boy in Northern California accidentally downloaded the $999.99 BarMax bar exam preparation application (iTunes link) using an iPod touch. He didn't mean to make the purchase and was surprised when it started to download the 1GB app. His mother was equally shocked, especially after she learned the price and that her son had not been prompted for an iTunes password.
They paused the download and went to an Apple store but were told that the store couldn't help. However, the boy's mother then emailed Apple and received a return phone call telling her that they would receive a full refund.
