GreenPois0n RC5 released to jailbreak iOS 4.2.1 [Updated]

Abpout 1.5 months ago, Apple announced iOS 4.2.1 for the Apple iDevices. We had told you that the Chronic Dev Team was working on a newer version of GreenPois0n to jailbreak iOS 4.2.1.

Now the Chronic Dev Team has finally released GreenPois0n RC5 which fully untethers the jailbreak on iOS 4.2.1 for all iOS devices. The iPhone Dev Team released redsn0w 0.9.7 which requires iOS 4.2b3 hashes and is currently for Mac. But, GreenPois0n RC5 doesn’t require you to have SHSH blobs of 4.2b3 saved on Cydia. You can jailbreak any iOS device with iOS 4.2.1 running on it.

Here are two good guides from RedmondPie.com which will help you to jailbreak iOS 4.2.1:

• How to Jailbreak iPhone 4 (1.59.00 Baseband) Untethered on 4.2.1 with GreenPois0n RC5 and Unlock with Ultrasn0w

You’ll get Cydia on your iOS 4.2.1 once you jailbreak with the above method.
