Hi, my contract with AT&T for my iPhone 4 is about to expire. But before it ends, I am planning to jailbreak and unlock it so that I will be able to use a T-Mobile SIM card. A friend told me to jailbreak my iPhone using Redsn0w 0.9.6RC16 and then unlock it with Ultrasn0w afterwards. However, some blogs and websites are suggesting that Redsn0w is not for unlockers. Now I am very confused, what tool should I use to jailbreak and unlock my iPhone?

If your baseband is not present in the supported list, then there’s no software unlock for you. Anyways, you can check this blog post to download and to know more about Sn0wbreeze 2.7.1 and PwnageTool 22.214.171.124. Then follow this step by step guide on how to unlock iPhone using Ultrasn0w 1.2.3.
If your iPhone is NOT running unlockable baseband, you will still be able to unlock it using Gevey SIM Pro.
