Following yesterday’s release of iOS 4.2.1 by Apple, everyone’s favorite team of Apple hackers, the iPhone Dev Team, have released Redsn0w 0.9.6b4 which provides a tethered jailbreak to all of the latest iOS devices and an untethered jailbreak to older devices like the iPhone 3GS and 3G and iPod Touch 2G. It is a full jailbreak that gives users access to the Cydia repository on their devices so they can use all the non-Apple approved apps they would like. Full instructions on how to apply the jailbreak available at the source link. Have you been holding off updating your iOS device waiting for the dev team to release a jailbreak? Planning on installing Android on your iPhone running the latest iOS software? Let us know in the comments!
For those of you who don’t know, Redsn0w 0.9.6b4 is based on Geohot’s Limera1n bootrom exploit which has already pwned all current iOS devices for life. The only problem is that it is a tethered jailbreak, which means you will have to boot it into a “jailbroken state” on every reboot. This so called tethered or semi-tethered jailbreak condition in Redsn0w 0.9.6b4 however only applies to the new devices like: iPhone 3GS (new bootrom), iPhone 4, iPad, iPod touch 2G (MC Model), iPod touch 3G and the iPod touch 4G. Old devices like iPhone 3GS (old bootrom), iPhone 3G and iPod touch 2G (Non-MC Model) can be jailbroken-untethered right now using this latest version of Redsn0w. So until and unless Comex of Spirit and JailbreakMe fame comes up with another untethered hack for iOS 4.2.1, the jailbreak we get for the newer devices will be tethered (or semi-tethered).
