4G and iPad. It is capable of Jailbreaking iOS versions 3.2.2-4.1 (RC4) and iOS 4.2.1-4.2.6 (RC6.1). It uses mainly Limera1n Boot-ROM exploit (originally SHAtter Boot-ROM exploit),for untether (ability to reboot device without connecting it to a computer and re-execute Jailbreak) user-land (software) exploits named "Packet filter kernel exploit" for 3.2.2-4.1, and "HFS" exploit on 4.2.1-4.2.6. Even though the untether exploits where for iOS 4.3-4.3.3, Greenpois0n was never updated to support those exploits, because of overwork on development of the Boot-ROM exploit for the iPad 2
. It uses usb_control_msg(0xA1 ,1) for the iPod touch 2G.
user-land jailbreak by the iPhone Dev Team member Comex (Nicholas Allegra), capable of jailbreaking the iPad's firmware 3.2 and iOS 3.1.2 and 3.1.3. The Chronic Dev Team has continued working on Greenpois0n, even after iOS 3.2.1 was released for the iPad and iOS 4.0/4.1 for the iPhone and iPod touch.
devices. It was declared to take time until greenpois0n with SHAtter and a user-land untether came out to jailbreak iOS 3.2.2-4.1 untethered. SHAtter and its untethered jailbreak in greenpois0n to jailbreak iOS 4.1/3.2.2 was all set to release on October 10, 2010 at 10:10:10 PM. But one day before the intended release of SHAtter, the well-known Hacker GeoHot released Limera1n. Initially for Windows, it has a different Boot-ROM exploit, the Limera1n exploit, and another untether by Comex. To prevent getting SHAtter burnt for nothing (to have future devices vulnerable to it) and because Limera1n supports more devices than SHAtter , the Greenpois0n release date was delayed by 2 days to make the Greenpois0n exploit with limera1n instead of SHAtter and to fit with the new untether. Finally, Greenpois0n was released on October 12, 2010.
into device to make an untethered jailbreak. This jailbreak had many bugs , including failures with Bluetooth
(until beta 5), GPS, VoIP (until beta 6) and many more. This jailbreak had 6 betas and was the first one of its kind, because of the delay of the 4.2.1 untether. There were plans for a windows release and supporting the 4.1 kernel instead of the 4.2b3 kernel. Those versions of redsn0w monte never came out.
/HFS exploit. this jailbreak worked on all devices that support iOS 4.2.1 except of iPhone 3G, and 24kpwn was still used for old-bootrom iPhone 3GS and iPod touch 2G MB (allowed custom bootlogos and shortened the boot process) This exploit was not saved for iOS 4.3 because it was patched already in the betas, due to Apple
's implementation of an ASLR. the exploit works up until iOS 4.2.8 (Verizon iPhone 4), but the jailbreak works up to iOS 4.2.6. Greenpois0n RC6 was released on February 18, 2011 to create an untethered jailbreak on Apple TV 2G 4.2.1(Apple TV 4.1.1) and later Greenpois0n RC6.1 to fix iBooks
drain issues on all Release candidates. Greenpois0n is not as stable as redsn0w, which uses a different method then Greenpois0n. Also, Greenpois0n can never make a tethered jailbreak, while redsn0w can and makes a solution for users who don't have the an untethered jailbreak available on the device.

iOS 4.2.1 untethered jailbreak
On November 22, 2010 iOS 4.2.1 was released for the iPhone and the iPad and brought iOS 4 support for the iPad, with Multitasking and folders and many more features like AirPlay and AirPrint. iOS 4.2.1 also blocked Packet filter Kernel exploit, used for untethered jailbreak on iOS 3.2.2-4.1. The only devices capable of untethered jailbreak on iOS 4.2.1 were the old Boot-ROM iPhone 3GS, iPod touch 2G MB model and iPhone 3G, which had untethered Boot-ROM exploit (24kpwn for iPhone 3GS and iPod touch 2G MB and Pwnage +Pwnage 2.0 for iPhone 3G) and a tethered jailbreak for all the rest of the devices, with Limera1n exploit and a tethered boot. Those where done by Redsn0w of the iPhone Dev Team.Jailbreak Monte
After one month with no update on iOS 4.2.1 untethered jailbreak, the iPhone Dev Team has released Redsn0w monte, which used SHSH (Signature Hash blobs) from iOS 4.2 beta 3, which was still vulnerable to Packet filter kernel exploit, and used usbmuxd to port the 4.2b3 kernelKernel
