Apple is offering a recall on the Ultracompact USB power adapters.  The problem that is noted is the metal prongs can break off into the electrical outlet.  They are exchanging these free of charge and affects the adapters that come with the iPhone 3G and the one you can purchase separately.  The affected countries are the USA, Japan, Canada, Mexico, and Several Latin American Countries.  The new adapter has a green dot to indicate the difference.  You can also see the prongs have changed a little.

 

They just don’t make em’ like they used to…
