Well the 6th beta of Redsn0w 0.9.7 has been released. This version fixes all Skype related issues which were hampering users ever since the first beta of this untethered iOS 4.2.1 jailbreak.

The iPhone Dev Team has released yet another update to Redsn0w 0.9.7 jailbreak tool. This new version fixes all sandbox-related issues, including Bluetooth problems on an untethered iOS 4.2.1 jailbreak. Also added is an “anti-piracy plea” note as a warning for those of you who are pirating iOS 4.2 beta 3 firmware.

Redsn0w 0.9.7 beta has been updated today, eliminating the need of externally running usbmuxd process which plagued many Mac OS X users. Everything else remains the same. Bluetooth functionality is still disabled.

MuscleNerd of iPhone Dev-Team has confirmed today that the next version of Redsn0w will include an option which will allow you to untether your iPhone jailbreak on iOS 4.2.1 without having to restore your device.

Earlier this month, Comex of Spirit and JailbreakMe fame confirmed that a more efficient userland-based untethered jailbreak method for iOS 4.2.1 will be released before Christmas 2010.
