Sherif Hashim, the guy who found the exploit to unlock 05.12.01 / 05.13.04 baseband on iPhones running iOS 4 is back with a video, which shows us how to activate iPhone 4, iPhone 3GS and iPhone 3G without the original SIM card. You can use any SIM card you like ! iPhone 4 users though will have to cut SIM to micro-SIM card size before using it.
