iPhone Dev Team have just posted new details of the new iOS 4.2 untethered jailbreak and baseband 05.14.02 and 02.10.04 unlock. iOS 4.2 will be released on Friday with a lot of new features.

By all accounts, we’re within a few days of Apple’s official public release of Firmware 4.2. Here’s all what you need to know :

- Thanks to geohot’s limera1n exploit, and our original pwnage2 exploit, and pod2g’s ipod2g-MC exploit, absolutely all devices at all iOS devices at all

- The untethered jailbreak of the very latest FWs and devices depends on @comex hacks. His hacks so far extend only to 4.1 and 4.2beta3. He’s working on a way to extend it to 4.2 and beyond. Just wait for him to work out his method.

- 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.

What does this mean to you ?

- If you’re an unlocker, just stay where you are. Please, just stay where you are. Any mistakes you make now may be permanent.

- If you only care about the jailbreak, feel free to experiment but keep in mind that any mistake you make may result in you losing pictures or notes or bookmarks that you’d rather keep. Honestly unless you love living on the bleeding edge, it’s better to just wait for official updates from Cydia/redsn0w/PwnageTool.

- Don’t buy or donate to any unlock or jailbreak scammers. Every legitimate solution you will find for unlocks or jailbreaks will be offered without an extended hand. That’s how this community works. It’s about freedom, not donations.

iPhone hacker comex could make untethered jailbreak until iOS 4.2 beta 3 and is working on extending it to final iOS 4.2. iPhone 3G / 3GS will get Ultrasn0w unlock once iOS 4.2 is released while iPhone 4 will get it a bit more but as soon as possible.
