If you bought an iPhone 3G or got one of the nifty tiny USB power adaptors from Apple recently from the US, Japan, Canada, Mexico, or one of several Latin American countries then you might want to stop using it.
Apple has identified some situations where the metal prongs might break off and stay stuck in the power outlet. They will begin replacing the adaptors come October 10th, either via a mail-in program or in an Apple retail store. In the meantime use any other adaptor that you might have or the USB docking cable that came with the phone directly to your computer.
