Wireless internet for Macbook Pro

Alright, so I've recently acquired a Macbook Pro. I'm on the road a lot, and need a way to get internet on there, so I can take it wherever and have internet. I know I won't be able to get it EVERYWHERE. But I really don't have the time to buy a modem/router and set it up that way. I know the MBPs have card slots, so would I go about it that way?

What are my options, and what do you all recommend?

Thanks!

Honestly, I am not sure if what Cingular and Sprint offer are compatible with OS X at this time.

If ye can put up with slow expensive connections then just access the net through your mobile phone and your laptop via bluetooth and GPRS

The specs for your MBP. You already have ethernet connection, wireless and bluetooth capability built-in. What are you asking?
