All of those smurfberry sales have led angry parents to sue Apple over its in-app purchasing policies, thanks to kids racking up credit card bills via iTunes. The problem is that minors playing free games on the iPhone or iPod touch made headlines when hundreds or thousands of dollars in in-app purchases was showing up on their parents' credit card bills.
One notorious game is Smurf Village from Capcom Interactive, which allows the purchase of a $99 wagon of smurfberries. The lawsuit, filed in US District court in San Francisco, states that "these games are highly addictive, designed deliberately so, and tend to compel children playing them to purchase large quantities of Game Currency, amounting to as much as $100 per purchase or more."
