[From Rich] Thanks to Rich for the heads up and it seems that Gizmodo are stating that the 3G iPhone can be unlocked using a SIM Card Adapter. "Just four days after its launch, the iPhone 3G has been unlocked for the first time exactly like the original iPhone: using a special card that piggybacks to your SIM card, fooling the phone into thinking it's using an official carrier. While this is not the software unlock being developed by the usual suspects, the video clearly shows that it works fine." Gizmodo after the jump.
