One of the developers enabled a passcode lock in iPad SDK and then decided to type it incorrectly for a few times. After 5th try iPad proposed to make an emergency call.

This option looks pretty obscure but can be explained as a following to FCC regulations, that demand wireless phones to be able to make emergency calls (even in the cases when the device isn't currently active or assigned a number).

Jobs claimed at the iPad's keynote that it has a built-in speaker and mic, so does it really can make normal calls in addition to emergency calls?
