Well I’m not sure why this is released, but probably to serve those impatient folks with very short lifespan left. iOS 4.2.1 was still in GM seed, and now the Dev-Team has come up with a new redsnow version 0.9.6b4 jailbreak, which is based on Geohot’s Limera1n bootrom exploit. This is still not a final jailbreak as it still needs tethering. That means requiring your iPhone4, iPad, and newer iPhone 3GS and iPod touch to reattach to a PC or Mac to boot into a jailbroken state each time your device loses power or needs a reboot. Not as simple as navigating to a site and jailbreaking with a swipe. Our recommends is to hold off for now, until the ‘untethered’ version is out. But if you’re the curious type or the impatient type with aging white hairs, you can still have a try with it by following the link at the source.
