How to Carrier Unlock iPhone 4 on iOS 4.3.3 After JailbreakMe 3.0?

Hello guys, I have just jailbroke my iPhone 4 for the first time using JailbreakMe 3.0. My iPhone is currently running on iOS 4.3.3. So what do I need to do to unlock it with Ultrasn0w?

Asked by: Christopher from Henderson, Nevada

Hello Christopher, there’s no way for you to unlock your iPhone from its carrier using Ultrasn0w software-based unlocking tool for the reason that your iPhone is already running on 04.10.01 baseband, which is not supported by Ultrasn0w. For your information, unlocking an iPhone is baseband dependent. And this is the reason why iPhone users who have unlockable baseband are advised to jailbreak their mobile phone using either Sn0wbreeze (Windows) or PwnageTool (Mac OS X) to preserve their baseband from getting upgraded.

Any alternative for Ultrasn0w software-unlock? Yes, and this is your last resort to unlock your iPhone. You can use Gevey SIM Pro to unlock your iPhone. If you aren’t aware, Gevey SIM is a special SIM case that is capable to unlock your iPhone (on any baseband and any firmware) by simply dialing the 112 emergency number. So to unlock your iPhone, just simply pop the Gevey SIM together with your preferred SIM card (micro / cutted SIM) into your iPhone 4 and follow the instruction provided by Gevey SIM. You can refer on this blog post for detailed tutorial regarding unlocking iPhone 4 on iOS 4.3.3 using Gevey SIM Pro. On the other hand, since you have hacktivated your iPhone after jailbreaking it using JailbreakMe 3.0, you should activate your iPhone 4 first before unlocking it. You can easily activate your iPhone 4 by using SAM.
