Just like the first generation of iPhone, the new iPhone 3G claimed to be unlocked via the sim card method. DesbloqueioBr has demonstrated the method to Engadget in video. Different from the iPhone-dev hacking, the unlocking programming is stored in a customize card which will need to be attached together with the sim card.

Once the altered sim card inserted into the iPhone 3G, you just need to key in the PIN number to unlock the phone. Is this going to be commercial in your nearby store? The company plans to release more info in the next few days. Check out the video below.
