What are the iphone 4 cases available free from apple?

[Clayton]

Because of the antenna issues Apple is giving free cases to anyone who purchases and iPhone 4 until September 31, 2010. What are the options of cases Apple will give you free?

You have to speak with the people at apple store i think.

Its not a case, its a bumper, a rubber frame that goes around the phone
