Several users probably remember TurboSIM, those cards making possible to use first generation iPhone on non exclusive carrier.
Those products are now back and fully functional for the iPhone 3G as reported by the French website FrenchiPhone according to a test performed with a Yessim. This card is commercially available and known as the Furiousim.
As there is no interest of purchasing a subscription-free iPhone 3G from USA or UK, this card will be very useful for users traveling in different countries, and not willing to pay the high cost of roaming, as this TurboSIM will allow the use of local networks.
