GreenPois0n RC5 RC6 Final is finally released and provides untethered iOS4.2.1 jailbreak for iPhone, iPad, iPod Touch G3/G4 and Apple TV. It does not require the iOS 4.2b3 SHSH blobs, and right now ONLY works with Mac OSX operating system (Windows version to come very soon can be downloaded here). GreenPois0n RC5 RC6 Final will also support animated custom boot logo on iPhone, iPad and iPod touch.

Download here for the Mac OSX version. The steps are straight forward. Simply follow the on-screen instructions. Once installed, you will see Loader app on the home screen. Launch it to begin installing Cydia (WiFi required).
Note: For those who are new to jailbreaking and unlocking, this will only jailbreak your device, not unlock it. We’re still waiting for the unlock for iPhone 4 with baseband 2.10.04, 3.10.01 and 4.08.00.

does this unteather a 3gs that has been jailbroken with the ipad baseband?
yes, please let us know how it goes if you intend to use this
I was just about to do it, then I saw that it doesn't unlock.
Im a bit unsure, will i be able to unlock my 3gs after? or is it only i phone 4 that there is no unlock for.
if you're on 5.14.02 or 5.15.04, those cannot be unlocked, the only way is to implant iPad's baseband 6.15.00
Hello guys, I too have an iphone 3GS, 4.2.1, 05.14.04. I understand I have to implant iPad's baseband to use the unlock. So am I running redsn0w first to upgrade to 06.15, then running Greenpois0n rc6 to jailbreak, then running ultrasn0w? Is that the right order? Also I'm using windows. Thank you!
that's correct, good luck!
I used 4.1 for 3GS using the ipad baseband and all are smooth, am planning to used the 2_5.0.1 FW with ipad baseband too for upgrade, ipad baseband automatically 6.15.01
Cheers!
works :)
No it didn't work with 3GS Unlocked and jailbroken
hard reset your iPhone first
hello!, I’m new on here and glad to be a part of the discussion
