Users are beginning to receive replacement iPhone chargers offered under Apple's product recall, which states:
"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."
Included with the replacement adapters is a return envelope, in which the old, defective adapters are to be placed and returned to Apple. Users have said that paperwork included with the replacement adapters states that a $29 fee will be charged if the old adapters are not returned.
