We had recently informed that you can unlock your iPhone 4 basebands 2.10.04 / 3.10.01/4.10.01 with Gevey SIM interposer, which costs you 70$ – 90$, and there is currently no software based iPhone 4 baseband unlock solution from The Dev Team. So this SIM is just like Gevey SIM Interposer, with the name of “REBEL Micro SIM-Card”. It will unlock iPhone 4 on iOS 4.0.1,4.0.2, 4.1, 4.2.1, 4.3 and 4.3.1 having basebands 1.59.00, 02.10.01, 03.10.04 and 04.10.01.
Rebel Micro SIM-Card will be releasing at Gadget Show Live in April and will start shipping from April 6th. Rebel sim-card is using almost similar technique as GEVEY interposer uses. It does not require to jailbreak your device and costs bit less than Gevey SIM, it will available in the market on the release with cost of 65$.
Note: MuscleNerd the vocal member of iPhone Dev team has already confirmed that the Use of GEVEY SIM interposer is illegal in USA and probably other countries where 112 is emergency call number, and use of GEVEY SIM may banned you from carrier, for more detail check out our complete post!
