After much success of the Gevey SIM interposer unlocking solution for iPhone 4 baseband 2.10.04, 3.10.01 and 4.10.01, Applenberry released Gevey Pro which brought bug fixes and is compatible with more SIM cards. Now, good news is that Applenberry has announced that they will henceforth be shipping Gevy Pro worldwide meaning that you will now be able to unlock iPhone 4 baseband 2.10.04, 3.10.01 and 4.10.01 in any country.
Gevey SIM was the first method to unlock iPhone 4 baseband 2.10.4, 3.10.01 and 4.10.01 through forced baseband activation using the emergency dialer. Then, came Rebel SIM which also offered the same service. However, it has been said the Gevey SIM is illegal in US and may also be in other countries as well.

Gevey Pro comes with a custom SIM tray and will not void your warranty. Also, you don’t need to jailbreak your iOS device for unlocking iPhone 4 using Gevey Pro.
If you’ve grown weary of waiting for the software based unlock for iPhone 4, you can use Gevey Pro to unlock your iPhone 4 on baseband 2.10.04 / 3.10.01 / 4.10.01 even on iOS 4.3.2 in any part of the world.
