If you bought an iPhone 3G in the US, Japan, Canada, Mexico or Several Latin American countries you may need to ship it back to Apple and get a replacement.
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.
Apple has called the program the “Apple Ultracompact USB Power Adapter Exchange program“.
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.
You have two ways of getting a new Apple Ultracompact Super Duper USB Power adapter thingy. You can either order it via the web or take in your current one to an Apple store after October 10th. Your new adapter should have a little green dot on the plug side as shown to the right. I was hoping it would be one of those cool fold up plugs, but it looks pretty much the same, only it won’t suffer “detached blades”.
