Hello guys, I am totally noob regarding jailbreaking and unlocking iPhones. I am currently using a pre-owned iPhone 4 running on iOS 4.3.5 and with 04.10.01 baseband installed. I have already done some research and have found out that this baseband is not supported by Ultrasn0w. Anyway, I am thinking to jailbreak and unlock this phone from AT&T. What is the best unlocking and jailbreaking tool for this phone? What do I need to do to achieve it? Thanks.

However, these jailbreak tools have no capability to jailbreak your iPhone 4 due to the fact that your iPhone is already running on unsupported firmware – iOS 4.3.5. Anyway, the only option available to jailbreak your iPhone 4 is via Redsn0w 0.9.8b4. But you should be noted that this version of Redsn0w offers tethered jailbreak only. Meaning, once you turned off or reboot your iPhone you will need to connect it to your computer in order to power it on. Anyway, the step by step and the download link for Redsn0w 0.9.8b4 can be found here.
Regarding unlocking your iPhone, since your iPhone’s baseband is not supported by Ultrasn0w, you can use Gevey SIM Pro to unlock your iPhone 4 on iOS 4.3.5. The tutorial on how to use Gevey SIM Pro can be found here. But first, before you unlock, you will need to activate your iPhone to iTunes using your original SIM card or with SAM app.
