Apple has determined that under certain conditions the new ultracompact Apple USB power adapter's metal prongs can break off and remain in a power outlet, creating a risk of electric shock. We have received reports of detached blades involving a very small percentage of the adapters sold, but no injuries have been reported.

The ultracompact USB power adapters were supplied with every iPhone 3G sold in the following countries, and may also have been purchased separately as an accessory:

US

Japan

Canada

Mexico

Several Latin American countries (click here for a detailed list of countries)

Note: Apple USB power adapters supplied with original iPhones or supplied with iPhone 3G units sold in other countries are not affected.

Customer safety is always Apple's top priority, and therefore we have voluntarily decided to exchange every ultracompact power adapter for a new, redesigned adapter, free of charge.

Users with ultracompact power adapters should immediately stop using them until they exchange them for a new, redesigned ultracompact adapter.

In the meantime, they should charge their iPhone 3G by connecting it to their computer with the USB cable that came with their iPhone or by using a standard-sized Apple USB Power Adapter (with fold up prongs) or with a third party adapter designed to work with the iPhone, such as a car charger.
