iPhone Dev Team has released another beta Testing Version of their Untethered Jailbreak of iOS 4.2.1 RedSn0w 0.9.7b5. This Beta fixes Bluetooth bugs found in earlier betas (and any sandbox-related issues should be resolved too). Sorry for all Windows users, RedSn0w untethered for Windows is still in the works and iPhone Dev Team will not release it in the Beta versions. Windows version of RedSn0w 0.9.7b5 is very slow that’s why iPhone Dev Team will not released until it gets speed up.
From iPhone Dev Team Official Blog:
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.
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.
Download RedSn0w 0.9.7b5 Here for Mac OS X If your device is currently jailbroken with one of the previous betas, please do a fresh restore first.
