Hit the "Phone" hardware key. That should open the regular dialer...now, you should be looking at a keypad, right? Look just below the keypad - in the center - there should be a little cellphone icon. Click that guy to hide the dialer and display the rest of your Call History.

You should be able to see your last two calls in the history in the Phone view without hiding the keypad.

I'll post two screen shots in a sec.
