Found over here is some information on a great looking Smartphone coming to the US. I want one.

But my problem is that I'm a bit of a neophyte when it comes to celluar technology in the US. Can I just take my current SIM card from my Verizon phone and insert it in the new phone? Will Verizon allow it? Do networks allow you to use any old phone?

I could probably just Google for the answer, but last time I tried, the signal to noise ratio was just too low...
