The iPhone Dev team has released new jailbreak tool for devices running iOS 4.3.1. The PwnageTool and redsn0w now brings untethered jailbreak for iOS 4.3.1 devices like iPhone 3GS, iPhone 4 (GSM), iPod touch 3G and 4G, iPad 1 and Apple TV 2G. Unfortunately, iPad 2 is still unsupported for a reason that the exploits used by limera1n and SHAtter cannot be used on Apple’s new tablet.

Users wanting to use the ultrasn0w unlock should stay away from the jailbreak until the iPhone Dev team gives the green signal after updating the ultrasn0w to support iOS 4.3.1.

It’s been few hours since iOS 4 went live and here we are with the jailbreak tool from the iPhone Dev team. The updated Redsn0w tool can now jailbreak iPhone 3G and iPod touch 2G devices running iOS 4 to allow you to install 3rd party apps outside the Apple App Store.

The tool is available for both Windows and Mac and comes with a fair ‘beta’ warning, which means you’ll need to organize, reload and update Cydia after successfully jailbreaking from redsn0w.

iPhone Dev team has released the final build of its redsn0w jailbreaking tool. The latest v0.9.2 can jailbreak all iPhones and iPod touches and supports v3.x firmware. The jailbreak however, is with a catch as newer models will still have a tethered jailbreak, which means you’ll have to jailbreak again after you completely restart the device.

Redsn0w is recommendable if you’re looking to jailbreak (possibly unlock older models) or don’t want Cydia as an additional download.

The redsn0w tool is available now for both Mac and Windows.

Mac users waiting for the jailbreak solution can quickly head to the iPhone Dev blog to download the latest version of PwnageTool. The PwnageTool 3.1.4 for Mac OS X jailbreaks iPhone 2G/3G/3GS and iPod Touch 1G/2G running OS v3.1.2 which can also unlock by installing ultrasn0w via Cydia.

Yes, fellas they did it. After confirming the exploit a couple of days back, they managed to jailbreak the device. However, don’t get your hopes high to get this solution anytime soon because they are holding it back to keep Apple off the exploit that could enable them to patch and close the jailbreak exploit forever. Though iPhone-Dev’s reasoning is sound, I don’t think it would take much time for Apple to patch and end the cat and mouse game once and for all.
