Hi guys, I need some assistance in jailbreaking my iPhone 4 on the latest iPhone firmware while preserving its baseband. I have an iPhone 4 and it was jailbroken on iOS 4.3.2 with 03.10.01 baseband, and the device was unlocked using Gevey SIM. So, how can I update to the latest firmware and keep my baseband? Thanks.

Anyway, you can check out and download iOS 4.3.5 from this blog post. In order to jailbreak, of course you will need to download PwnageTool 4.3.3 from here, as well as the PwnageTool Bundle for iPhone 4, and the Tetheredboot utility. Once you have downloaded all the required software, you can follow our step by step guide on how to jailbreak an iPhone using PwnageTool and PwnageTool Bundle from here. Then after you have successfully jailbroke and preserved the baseband of your iPhone, you can check this tutorial on how to unlock iPhone 4 using Gevey SIM Pro.
