Guess the BlackBerry Game!

I remember when I got my first BlackBerry (such a momentous time in my life), and I never could have imagined that five years later, I would have worked my way through three more BlackBerry handsets. Well I did, and although I am a gadget addict in general, my CrackBerry addiction still reigns supreme. Now I'd like to think I could figure out what model a BlackBerry is with my eyes closed, but I still have my slip-ups every so often. What about you? Can you figure out which BlackBerry is which?
