Redsn0w 0.9.7b2 has just been released into the public redsn0w untethered jailbreak iOS 4.2.1 beta test program. The latest beta resolves some significant problems with the first beta, and the iPhone Dev Team says that 0.9.7b2 should resolve all the crashes that were occurring from the prior b1 release. Although the Bluetooth is still not going to work. The Dev Team also suggests that if testers had any trouble using usbmuxd with beta1 that they should wait until the software is integrated directly into a coming release of redsn0w itself.
