Travel in France, Italy, and Switzerland . .unlock and buy SIM?

Hey - going to Europe from the US in a few weeks and will be in the countries listed in the title. Looked up the ATT rates for the phone. . .way too expensive. Can I just unlock the phone (3.0 OS) and then buy a SIM when I get to Switzerland and use for a few weeks?

Provided it's not a 3GS you can, though you'll need to buy a different SIM in each country.

Buying a prepaid SIM there would be the way to go. http://www.prepaidgsm.net/ is a good research tool. And yes, generally, you would be better off buying a SIM in each country. Be aware that data rates are pretty brutal in Europe, but sometimes deals can be had.
