The iPhone Dev Team has confirmed that a Windows version of Redsn0w 0.9.7 is on its way for jailbreaking iOS 4.2.1 with iOS 4.1 IPSW instead of iOS 4.2b3 firmware and SHSH blobs.
The iPhone Dev-Team has successfully ported “Monte” technique back to iOS 4.1. This will enable users to untether the iOS 4.2.1 jailbreak on iPhone, iPad and iPod touch without having 4.2b3 SHSH blobs saved on Cydia.
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.
One of the most annoying bug of initial release of Redsn0w 0.9.7 was the native app crashes which made using the Task Switcher, iPod and YouTube apps unusable after the untethered jailbreak. Well with the latest release of Redsn0w 0.9.7b2, all these problems have been fixes. Bluetooth functionality though is still disabled.
