Apple is recalling the iPhone 3G Power adapter.
"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. Users with ultracompact power
adapters should immediately stop using them until they exchange them
for a new, redesigned ultracompact adapter."
