The iPhone Dev Team has released redsn0w 0.9.7b1 over the weekend, which provides an untethered means to jailbreak both the iPhone 4 and iPad running on iOS 4.2. Do note, however, that this is still a beta tester program so expect some hiccups along the way. They also warn that Bluetooth functionality is disabled here due to “some sandbox issues with Bluetooth” and this only work on a Mac OS X system. iPhone unlock dependents are also advised to stay clear of this version of redsn0w.
