Apple has issued a recall for the ultra-compact USB Power Adapter that ships with the iPhone 3G. In a statement, the company acknowledged that “under certain conditions,” the device’s little metal prongs can break off, get stuck in the power outlet and potentially give you a very bad electric shock.

Affected adapters were sold with iPhones in the US, Canada, Mexico, Japan and several Latin American countries. Apparently, this is the result of a fairly poor design approach used to save money. No injuries have been reported, but Apple is urging iPhone 3G customers to bring their adapters to an Apple store for an exchange and in the meantime charge via USB through their computers.
