Apple released iOS 4.2.1 and iPhone Dev team released Redsn0w 0.9.4b4 to jailbreak iOS 4.2.1 Besides a successful jailbreak you can not unlock at this time. As you know, an exploit in the baseband (modem firmware) is required to develop iPhone unlock. Sheriff Hashim already announced that he found such an exploit. The iPhone Dev Team confirmed in their recent blog post, that an unlock for the iPhone 3G and iPhone 3GS is expected this week. iPhone 4 unlock appears more and more difficult.
- iPhone 3G and 3GS unlockers will be covered by our upcoming unlock. Stay away from any updates to Apple FW until our official release and you’ll be okay. Just stay away from all Apple IPSWs 🙂
- iPhone4 unlockers are not left out in the cold. @sherif_hashim has found some very promising avenues to pursue. Those will be explored as soon as possible after all the 4.2 madness.
