Good news for iPhone 4 users. Soon you will be able to unlock your iPhone 4 on all basebands by using Rebel Micro SIM-card. Just like Gevey SIM, Rebel Micro SIM-card will bypass the network lock and it will unlock iPhone 4 on basebands 1.59.00 / 03.10.01 / 02.10.04 / 04.10.01 running iOS 4, iOS 4.1, iOS 4.2, iOS 4.2.1 and iOS 4.3. You don’t need to jailbreak your iPhone. Rebel Micro SIM-card is going to launch at the Gadget Show Live in April.
You have to pay $65 USD for Rebel Micro SIM-card which is less than GEVEY SIM. The shipping of Rebel Micro SIM-card will start from 6th April. You should note that you have to call an emergency number to unlock iPhone 4 using Rebel Micro SIM-card which is illegal. So it is recommended that you should wait for the Ultrasn0w unlock of iPhone Dev Team.
