Engadget has taken a crack at the SIM card unlock discovered by some guys down in Brazil. While this hack uses the TurboSIM card that the original SIM hack used, it does not require that any software be installed on the device, meaning that it does not require you to jailbreak your iPhone 3G. All it requires is a specially programmed chip. They tested it out using a Fido-locked iPhone 3G and took a video of the process, which you can check out here.
Four days after it's launched, the 3G iPhone has been "unlocked". Well, not exactly, but people have gotten it to work on other networks a special card that makes it think it's using an official carrier. It's not a software unlock yet, but it's a start. This is also the first unlock method for the first iPhone (that didn't involve opening it up and tinkering with hardware). Video after the break.
