Audiovox SMT 5600 / SPV C500 (HTC Typhoon)

I just got an unlocked 5600, and it works fantastic, except that I can't figure out how to enter punctuation. On my other phones, when I would cycle through text entry modes (abc, 123, T9, etc), one mode would be punctuation, but that doesn't seem to the case on the 5600. So how do I enter punctuation?

Thanks,
Erick
