Can I Unlock iPhone 4 Baseband 4.10.01 on iOS 4.3.3?

I’m planning to unlock my iPhone as I am all set to South East Asia next month. I have no other phone expect for this one and has no plan to get another phone. So I asked a technician to unlock my iPhone for me. But, unfortunately, he wasn’t able to unlock it. According to him, my iPhone 4 is running on an unlockable baseband and Ultrasn0w cannot unlock it. Anyway, my iPhone 4 is on iOS 4.3 baseband version 4.10.01. Are there any possible way / alternative available to uncloak my iPhone? Thanks.

Hello Patricia, at the moment, you will not be able to unlock your iPhone 4 due to the fact that its baseband has been updated and even the latest version of Ultrasn0w carrier unlocking tool has no capability to unlock your iPhone from it contracted mobile phone carrier. Since it is obvious that you cannot wait for the iPhone Dev team to work / release the new Ultrasn0w for new iPhone baseband, then you have to get Gevey SIM / Gevey Pro to unlock your iPhone 4 so that you can start using your iPhone 4 on any mobile phone carrier, locally and abroad.  To unlock your iPhone 4 using Gevey Sim, all you need to do is put your SIM card and Gevey SIM in the same tray and then pop it in, wait fir few minutes and you are done. You can refer on this post for detailed iPhone unlocking tutorial using Gevey SIM. But, be careful as there are tons of fake SIMs all over the Internet. So I would recommend you to order your Gevey SIM from the creator and official distributor of Gevey SIM that is

I would also recommend you to jailbreak your iPhone first before unlock it to make other features working smoothly. You can follow this tutorial to jailbreak your iPhone 4 using JailbreakMe 3.0 or Redsn0w 0.9.6rc16.
