Yesterday we got 3 beta versions of Redsn0w 0.9.7 to untethered jailbreak for iOS 4.2.1, but some jailbreakers reported that usbmumxd process is not working with them, moreover the Windows users were left behind and couldn't untethered their devices.

Therefore, Dev-Team is now cooking the new beta to fix this problem which may be the last one. The good news is that in case this beta 4 looks stable with testers and free of bugs, they will release it (Redsn0w 0.9.7b4) for windows, thanks Dev-Team.

This indicates that we may see the public release of Redsn0w 0.9.7 very soon. More updates as they come ! Stay tuned !

UPDATE 1: [Video Guide] Redsn0w 0.9.7b4 has been released to Untethered Jailbreak Without the Need of ‘usbmuxd’ Process , check full details Click Here.
