Hi, I am planning to jailbreak and unlock my newly purchased iPhone 4. It is currently runs on iOS 4.2.1 with baseband 3.10.01 installed. Will I be able to jailbreak my iPhone 4 using JailbreakMe 3.0 and unlock it with Ultrasn0w 1.2.3? Please advice. Thanks.

But, of course, there’s always alternative. If you really want to unlock, then you can do it with the help of a special SIM case called Gevey SIM / Gevey Pro. Unlocking iPhone 4 using Gevey SIM is as easy as dialing 112 for 2 seconds from your iPhone. Just simply pop the Gevey SIM interposer together with your preferred SIM card (micro SIM or cutted SIM) into your phone and follow the onscreen instruction. You are unlock in a minute or two. You can follow this tutorial on how to unlock iPhone 4 on iOS 4.3.3 using Gevey Pro. But before you unlock, you should hacktivate your device first to make sure that all features of the iOS work smoothly on the unlock iPhone. You could easily hacktivate your iPhone 4 through jailbreaking it using Redsn0w 0.9.6 rc16 (since JailbreakMe 3.0 is quite buggy) and then activate it using SAM.
