iPhone or Blackberry Curve 8330?

Which is better? Is this a work Blackberry in Japan? Can I change my SIM card in a Blackberry? Why can not I be a very busy man with an iPhone? Can you watch live TV on an iPhone?

I honestly think if you want have fun with your phone to put emulators on it and watch live TV and video, you should go with the Iphone. but as a very busy person you should go to the black berry.
