Going to be in Italy (Firenze, specifically) for a week and would like to use my unlocked G1 while I am there (wife will be using her unlocked MyTouch 3G, too). Anyone have any suggestions for which carriers have the best deal for a short-term data plan (pay as you go is fine)?

I know that Vodaphone is there and I used them last spring in Croatia (pay as you go data on a USB Wireless stick and a phone, both! Was great!), but I figure there might be some variations from country to country, even within the same company.

Thanks!
