Hi guys, is there a way to unlock my iPhone 4 on iOS 4.3.3 with baseband 04.10.01 using Ultrasn0w? Where can I download the latest version of Ultrasn0w to unlock my device? I am really desperate to unlock this phone or I might opt to get an Android phone. Thanks.

Anyway, if you really want to unlock your iPhone, then you can use a hardware-based unlocking tool called Gevey SIM. With Gevey SIM, you can unlock your iPhone without needing to jailbreak your device. However, we recommend to jailbreak your iPhone 4 using Redsn0w 0.9.6RC16. You can download Redsn0w 0.9.6RC16 form here and the step by step guide on how to jailbreak iPhone 4 using Redsn0w can be found on this blog post. Then you can follow this tutorial on how to unlock iPhone 4 using Gevey SIM Pro. You should also activate your iPhone using the SAM or by your AT&T SIM card.
