The iPhone Dev-Team is getting close to releasing the final version of its flagship untethered jailbreak for all iOS 4.2.1 devices, redsn0w 0.9.7. The fifth beta of the jailbreak was released to beta testers via Twitter early this morning, and according to the developers, the new version squashes most Bluetooth-related bugs identified so far, as well as other minor bugs reported by beta testers. Good news for Windows users, the Dev-Team also announced that they are finally working on a Windows version as well. The beta 5 includes all the improvements brought to redsn0w 0.9.7 so far, such as video playback improvement, and FaceTime compatibility.
If you want to give redsn0w 0.9.7b5 a try, simply follow the Dev Team via Twitter. Note that the software is directly available on Google sites. If the beta 5 shows no significant bugs, the official version of redsn0w 0.9.7 for OS X could be packaged and released within the next couple of weeks. Meanwhile, a Windows port is finally in the works, but Windows users will have to wait a bit longer, as the Dev Team decided not to release the Windows beta just yet, mostly due to speed issues.
The fifth beta is now available (testers ONLY please!). Bluetooth is now working (and any sandbox-related issues should be resolved too). Please do not pirate the 4.2b3 IPSW! Only those enrolled in the iPhone Developer program have legitimate access to that IPSW using these links (the links won’t work unless you’re a legit developer currently logged in). There is actually a Windows version of beta5, but it’s excruciatingly slow compared to the Mac version because it’s forced to use files on your hard drive instead of RAM while it’s processing the very large IPSW images. It really is very very painfully slow, so we probably won’t be releasing it for testing purposes unless it can be sped up somehow.Interestingly enough, the beta 5 will ask you to take an “anti-piracy plea” before you can use it. The software requires the iOS 4.2 beta 3 IPSW files (iPhone/iPad/iPod firmwares) to jailbreak iOS-powered devices running iOS 4.2.1, and even though the files are available on most file sharing sites, only official iOS developers have legitimate access to them.
Even though jailbreaking is considered legal, always keep in mind that Apple sees it as a warranty-voiding act, so do it at your own risk. Please do not use jailbreaks to install copyrighted/paid content you haven’t purchased yourself.
