iPhone 3G Unlocked with SIM Card Adapter

Only days after the iPhone 3G phone was launched it has already been unlocked. The method isn’t software, it uses a card that piggybacks onto your SIM card, and it works. Breno MacMasi, the Brazilian hacker who unlocked his phone in the video said:

Our procedure consist in using one SIM adapter to simulate a fake IMSI test card. Instead of the AT&T IMSI like in the universals.

Breno’s method creates an International Mobile Subscriber Identity, which causes the phone to work on the network you want it to.
