A new (false...) italian MVNO:
Telepass.it: Autostrade per l'Italia - Telepass Mobile
"Telepass Mobile" by Autostrade is simply a tariff plan powered by Wind

"Telepass 10 e lode" in fact is the old "Wind 10"... not so bad, not so exciting.
Anyway me and Effendi just bought a sim card last saturday... hope to have soon special services on italian highways (
Autostrade per l'Italia - an asset of an Italian holding company, named Atlantia - is the largest concessionaire on the Italian autostrade/highway network) but honestly this simcard is not so useful.
If you are interested (and if you are travelling in Italy by car

) you can buy the sim card @ Punto Blu points (see the list:
http://www.autostrade.it/autostrade/puntiblu.do ), the simcard costs 5 € (5 € included).
I took some pictures on my blog too
