After releasing Redsn0w 0.9.7 beta1 & beta 2, iPhone Dev-Team has released 3rd beta of Redsn0w 0.9.7 for untethered iOS 4.2.1 jailbreak. The second beta was brought to fix all app crash issues (Springboard and Task Switcher). Redsn0w 0.9.7b3 fixes even more bugs, particularly the ones releated to non-GUI programs which handle media contents mainly. Issues related to FaceTime, Winterboard themes, and embedded videos in iTunes should be resolved now.
Here is the official change log from iPhone Dev-Team:
Update #3: The third beta is now available (testers ONLY please!). This version extends the fix made in beta2 over to the non-GUI programs too (like the daemons that handle media content). That should cover things like Facetime, Winterboard themes, and embedded videos in iTunes. If you had trouble using the usbmuxd in previous betas, please wait until we incorporate that into redsn0w itself (i.e. don’t bother trying this beta3, just wait for the integration).
As advised before, all of these betas are meant for testers and pros. Novice users should strictly stay away from trying Redsn0w 0.9.7 betas and should wait for the final version of Redsn0w 0.9.7. We'll keep you posted.
