We have already discussed the current status of jailbreak 4.1 and unlock iPhone 4.1 for iPhone 4 3GS [old and new bootrom]. The 4.1 jailbreak scenario is also same for iPod Touch 3G 2G [MC Models]. As per discussion, our hopes are lying with @comex whose userland jailbreak will likely release as Spirit Jailbreak 4.1 for iPhone 4 3GS and iPod Touch 3G 2G.
The early hints regarding upcoming GreenPois0n 4.1 Jailbreak has been complied here before actually iOS4.1 beta arrived. Right now, @pod2g and other iPhone Dev Members are probably busy in decrypting iOS4.1 and see whether Apple has surprised them with and circumvention to stop Spirit Jailbreak 4.1 from working on iPhone 4 3GS and iPod Touch MC models.
As iOS4.1 is in beta stage, we should not expect GreenPois0n jailbreak 4.1 to arrive because Apple can ´t fix the hole in upcoming public release. If Apple has not done something extraordinary in iOS4.1 then GreenPois0n 4.1 Jailbreak would be available to download after iOS4.1 public release.Download GreenPois0n
