Here is some good news and bad news for all the jailbreakers around the world. Greenpoison is based on SHAtter which is a tethered exploit, but Comex from the Dev-Team, made it untethered to develop the upcoming Greenpoison jailbreak for iOS 4.1. However, Greenpoison to jailbreak iOS 4.2 and iOS 4.1.1 will be a tethered jailbreak.


The untethered Greenpoison jailbreak will only be available for iOS 4.1 and iOS 3.2.2. 

Stay tuned to Mod Your Pod for latest updates on the issue.
