After yesterday's redsn0w 0.9.10 beta 2, today the Dev Team released the beta 3 version of the program with which we can untethered jailbreak our devices. This time the Dev Team solved the problems due to which applications dependent on MobileSubstrate did not work after restoring the jailbreak and until a reinstallation of the plugin. Here we also include ultrasn0w, so if you decoded with ultrasn0w and used redsn0w 0.9.10 beta 2 yesterday but the decoding won't work, it would be good to reinstall MobileSubstrate if you haven't done it yet.
Update #3: The b3 version of redsn0w fixes a problem where re-running redsn0w over an existing jailbreak would cause MobileSubstrate-based apps to stop running until MS was installed again. Now you can re-run the redsn0w jailbreak step without worrying about that (but still remember to de-select the “Install Cydia” option if it's already installed).
Theoretically, there is no need to use redsn0w 0.9.10 beta 3 now if everything is working correctly, but if you are thinking of jailbreaking again, it is recommended to use this latest version of the program. You can download redsn0w 0.9.10 beta 3 from here: Windows, Mac OS X. Jailbreak tutorial find here.
