Just like TurboSIM interposer by Gevey, Rebel has launched a new Micro SimCard which can unlock iPhone 4 baseband 04.10.01, 3.10.01 & 2.10.04 on iOS 4.3.1, iOS 4.3, iOS 4.2.1, iOS 4.1 and iOS 4.0. If you ask me for the difference between Gevey SIM and Rebel Micro SimCard, the only difference i can see is the price. You can buy Rebel Micro SimCard for U.S. $64 which saves you around 6 USD when compared to Gevey SIM's price.
So how does Rebel's Micro SimCard works? It works on the same principle used by Gevey SIM interposer which involves requesting a TMSI by calling 112 emergency number and then toggling flight mode ON/OFF which blocks electrical connection between the phone and the SIM. In this way emergency call overrides the network lock and activates the cell radio. Your iPhone displays "No SIM card installed" message before sending the spoofed IMSI and when you turn flight mode ON, the network is able to register you again because the TMSI you obtained earlier is still valid :P I have already covered the working of Gevey SIM in detail which you can read here.
So what's your choice? Gevey or Rebel? For those who don't know, MyDalle is already selling Gevey SIM for U.S. $53.80 which eliminates the only reason to buy Rebel's Micro SimCard instead of Gevey. Still if you are interested in buying Rebel's SIM, it will be available for order w.e.f. 6th April, 2011 from their official website.

Remember, the only permanent unlock solution for iPhone 4 is only through Dev-Team's NCK unlock method which will be available soon. Dev-Team has already done a lot of work on NCK unlock and hopefully if this method worked, it will unlock all iPhone 4s for life.
