greenpois0n has answered many prayers of jailbreakers today by providing an untethered jailbreak for iOS 4.2.1 for iPhone 4, iPhone 3GS, iPod Touch 3G, iPod Touch 4G and iPad. Along with this, there’s a surprise element in the Read Me file for greenpois0n RC5 which shows Verizon iPhone 4 in the list of supported devices but untested since obviously, the device hasn’t been released yet. What seemed like might be a long time to jailbreak the CDMA Verizon iPhone 4, seems like an early possibility now.
Check out the complete readme file below:
