A new iPhone unlocking method is discovered, which achieves a full unlock using only a Turbo SIM card. This latest method is a big improvement over the previous options such as upgrading or downgrading the software used in the iPhone etc. This new methot doesn't require you to buy anything besides a Turbo SIM card. Usage of the the Turbo SIM is very simple. Process basically involves copying the information from your AT&T SIM onto a Turbo SIM, then switching your AT&T SIM for your carrier SIM. This allows the Turbo SIM to piggyback on your carrier SIM, and apparently gives you full calling, SMS, EDGE and other capabilities. You can always use your original SIM and your iPhone's Hardware or Software is never touched or altered in this process.

The Turbo SIM is one of a large family of "Dual SIM" devices (HyperCard, StealthSim, MagicSIMetc.) that piggyback on a telephone SIM card to alter its normal operation. It is made by BLADOX, located in Prague, Czech Republic. It is a very thin device with a 9mm by 9mm eeprom mounted in the top right corner. It is pressed on top of a normal SIM card (with some plastic cut off) in such a way that it is still small enough to be inserted into the SIM card slot of any GSM phone. Without the product, the SIM card is still usable as before. It intercepts traffic between the cell phone and the original SIM card, and modify this traffic based on programming stored in the microcontroller.
