Fastweb is a landline operator and to get the € 9.90 offer you must subscribe with them before December 31st and you pay that little only till march, after that month, if you want unlimited internet, it's 65 euros per month... I think you must keep that subscription for minimum 2 years and you have to pay with banck account or credit card, which I suppose must be Italian. So I really guess it's not a great idea.

Much better to use a mobile service. 3 has quite a good offer to call US numbers: 15€/month to get 50 hours. You can also buy the Skypephone, it's a rather cheap 3G phone with Skype capabilities, if you refill every month you get free Skype calls to other Skype numbers (no SkypeOut calls by now).
