If you decided to unlock your iPhone 4, 3GS on iOS 5 so you have two ways the

• First way: is to use Ultrasnow 1.2.4 which has released by the Dev- team to unlock iPhone 4, 3GS on iOS 5 which supported these baseband 01.59.00 / 04.26.08 / 05.11.07 / 05.12.01 / 05.13.04 / 06.15.00.

• Second way: is to use Gevey SIM in order to unlock iPhone 4 on iOS 5 Gevey Sim supported baseband 01.59.00 / 02.10.00 / 03.10.1 / 04.10.1 but notes if you have an iPhone 4 that is currently unlocked with a Gevey SIM card, you can unlock your iPhone on the iOS 5 firmware with the same Gevey SIM card as long as you preserve your baseband while updating to the iOS 5 firmware. So the difference between UltraSn0w and the Gevey SIM card, is that UltraSn0w only supports a limited number of older basebands while the Gevey SIM card supports a limited number of newer basebands.
