We are unsure about release date of iOS 4.2 but it is going to be released within days. The iOS 4.2 is surely is a gigantic update for iPad to whom it will bring Multitasking, Folders, and Air Print. It will also bring relief for iPhone 3G users who have been complaining about iOS performance on their devices. For other iPhone versions and iPod Touch, it will bring some new features and fix.
It is obvious that a new jailbreak and unlock would be released once iOS 4.2 is out. It has been possible to jailbreak 4.2 firmware on iPhone, iPod Touch, and iPad on latest iOS 4.2 release candidate. However, it was doable because of Limera1n’s exploit and @comex’s userland bug. The untethered part is likely to gone with final release of iOS 4.2. However, iPhone Dev Team is working to bring untethered 4.2 jailbreak and more official details are
By all accounts, we’re within a few days of Apple’s official public release of Firmware 4.2. Here’s 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 firmware versions are capable of being jailbroken.
- The untethered jailbreak of those very latest FWs and latest 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 and you’re absolutely sure you have your personalized 4.1 SHSH hashes, feel free to experiment but keep in mind that any mistakes you make may result in your 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 the iPhone jailbreak/unlock community has succeeded. It’s about freedom to do what you want with your $300 device — not about donations, egos, tweets, or “interviews.”
To get an early iOS 4.2 jailbreak, you should have already saved SHSH Blobs on iOS 4.1 or early firmware. iPhone 4.2 unlock will be available for 3G/3GS at first. iPhone 4 users would have to wait.
