Apple has found that a USB iPhone charger sold in Europe between October 2009 and September 2012 is causing issues for some customers. The charger "may overheat and pose a safety risk." Nothing like a toasty iPhone charger to worry an Apple loyalist. 

While the malfunction was found only in "rare cases", Apple is still urging those who still have the charger to stop using it, and has offered to replace them free of charge. The image to the right will help you identify if you have the model in question.

The charger was sold in 37 countries throughout Europe, and several in Africa and Asia as well. The charger was shipped with iPhone 3GS, 4, and 4S, but was also sold separately as a stand alone charger.

This isn't the first charger issue for Apple. In 2008, Apple replaced defective 3G chargers and the more recent Lightning cable has caused issues for some iPhone owners
