Is It Possible to Unlock iPhone 4 on iOS 4.3.2 Firmware?
Last week, I jailbroke my iPhone 4 using Redsn0w and now I want to unlock it, so that I can use it with any mobile phone carrier as I am preparing to visit my girlfriend to Europe for a 3 weeks’ vacation. Obviously, the purpose of jailbreaking and unlocking the iPhone is to be able to pop in a SIM card from a local carrier there in order to make cheap calls around Europe. Is there any unlock method available for my device? Please help. Thanks.

Hello Dimitri, unfortunately, you will not be able to unlock your iPhone
4 using Ultrasn0w carrier unlocking tool as the Redsn0w jailbreak tool have updated the baseband version of your iPhone 4 to unsupported new baseband. You should be note that if you want to jailbreak an iPhone, you should STAY AWAY from Redsn0w (unless if you are an iPhone 3GS users who want to update to iPad baseband) or Greenp0ison
as these jailbreak tools has no capability to preserve the unlockable baseband of the iPhone. iPhone jailbreakers who rely on unlock should jailbreak their device sing either PwnageTool
(for MAC OS X) or Sn0wbreeze
(for Windows) as these jailbreak tools were specially designed to keep the iPhone baseband form getting upgraded so that it can be unlock using Ultrasn0w
But don’t lose hope, as you can still unlock your iPhone 4 using Gevey SIM. To unlock iPhone 4 using Gevey SIM, all you have to do is navigate to www.applenberry.com and order for your Gevey SIM interposer. Once you received it, follow this tutorial to unlock iPhone 4 on iOS 4.3.2 using Gevey SIM.
