Hi guys, I’m planning to get a new iPhone 4 that will work on China. Well, I am currently using a locked iPhone 4 here and it is running on iOS 4.3.5. I know that this version of firmware cannot be unlocked using Ultrasn0w and this is the reason why I need to get a new iPhone. Appreciate your help. Thanks.

Lastly, if you really want to save money, then you should unlock your existing iPhone 4 instead of getting a new one. Yes, you can still unlock your iPhone on iOS 4.3.5 but now with Ultrasn0w software-based unlock. You can use Gevey SIM Pro in order to unlock your iPhone 4 on iOS 4.3.5. If you aren’t aware, Gevey SIM has capability to unlock iPhone 4 from any carrier running on any iPhone firmware and baseband versions. Unlocking iPhone 4 form its mobile phone carrier using Gevey SIM Pro is easy as 1-2-3. All you have to do is pop in the Gevey SIM interposer together with your preferred SIM card (cutted or micro SIM) and dial 112 emergency number. You can refer on this blog post for detailed tutorial on how to unlock an iPhone using Gevey SIM Pro.
