Greenpoison 1.0 RC5, the first reliable jailbreak tool to achieve an untethered jailbreak of the iOS 4.2.1 Apple firmware, is now available for Windows users, mere days after its release on Mac OS X.

Softpedia can confirm that the Chronic Dev site has been updated with a download link for Windows users looking to grab Greenpois0n 1.0 RC5 and jailbreak their iPhone, iPod touch, or iPad.

Linux support is yet to be added, with no ETA provided by the Chronic Dev Team hackers.

Greenpois0n is known to not require developer saved SHSH blobs of iOS 4.2 beta 3.

All devices capable of running iOS 4.2.1 are supported by Greenpois0n 1.0 RC5.

In related news, Musclenerd of the iPhone Dev Team has confirmed a few facts for iOS jailbreakers and unlockers via his Twitter feed.

The hacker said that their popular PwnageTool jailbreak application might also support iOS 4.2.1 untethered jailbreak should they get a green light from Chronic Dev (to use their exploit).

In other words, expect PwnageTool untethered jailbreak for iOS 4.2.1.

Those who’ve employed the iPhone Dev Team’s redsn0w can now apply the Greenpois0n jailbreak without worries, Musclenerd added, and vice-versa also applies.

However, Apple is already on track to release iOS 4.3, going by the latest reports. Hopefully, for the jailbreak community, the iPhone Dev Team will step up its game and release compatible versions of its redsn0w and PwnageTool applications.
