Jailbreak Verizon iPhone 4 iOS 4.2.6 with greenpois0n RC5.4

A few moments ago, pictures were tweeted out of Cydia running on Verizon iPhone 4. This untethered jailbreak was achieved through greenpois0n although a few bug fixes were needed to make it possible. An updated version of greenpois0n, RC5.4 has been released which supports untethered jailbreak of iOS 4.2.6 on Verizon iPhone 4.

The method to jailbreak Verizon iPhone 4 is the same as the one we published earlier. The updated RC5.4 build is only available for Mac OS X so far but as soon as the Windows version is out, we’ll update you guys.

greenpois0n RC5 was released a few days ago as an untethered jailbreak for iOS 4.2.1 on iPhone 3GS, iPhone 4, iPod Touch 3G, iPod Touch 4G and iPad, first for Mac OS X and then for Windows. iOS 4.2.6 jailbreak on Verizon iPhone 4 was also listed in greenpois0n’s readme file as supported although it was untested prior to the release of the device. Apple TV jailbreak support is expected to be included in greenpois0n RC6 next.
