With every iOS release, Dev Team is trying to keep up by offering a suitable jailbreak tool to perform jailbreak on our devices. Since iOS 6 is not an exception, for those of you who want to upgrade their devices to the latest operating system released by Apple, Dev Team updated RedSn0w in order to perform jailbreak.
This jailbreak is supports only iOS 6 A4-based devices such as iPhone 4, iPhone 3GS and iPod Touch 4th generation only. As some of you may expect, since iOS 6 was just released a few days ago, RedSn0w 0.9.13dev4 performs only a tethered jailbreak. This means that you need to boot your device in a jailbreak mode each time it runs out of battery. This can turn out to be quite annoying, but your only solution to jailbreak your iOS 6 device. Besides this, users will not get Cydia. Unfortunately, as any other tethered jailbreak, RedSn0w does not install Cydia automatically. As developers pointed out, jailbreak 6 using RedSn0w 0.9.13dev4 covers only the beta versions of iOS and the latest 6.0 seed.
