The Chronic Dev Team will be releasing Greenpois0n RC5 very soon. Greenpois0n RC5 will be able to jailbreak all iDevices on iOS 4.2.1. Supposedly, Chronic Dev Team will be releasing an untethered jailbreak on iOS 4.2.1 without making the use of SHSH Blobs. p0sixninja, a member of Chronic Dev team earlier posted a demo video of jailbroken iPhone booting untethered running on iOS 4.2.1.





Have a look at p0sixninja's tweet below...

@poisixninja it’s 0x5A% done now
Sorry, We’ve been “wasting” our time for research for 4.3 rather then development. Awesome things coming in RC5 though!!



0x5A is hexadecimal for 1011010, so it is clear that Greenpois0n will be completed shortly. According to us, it will be released before the Geohot's RubyRa1n jailbreak which is to be released after Februrary 10th. What are your thoughts about this new Greenpois0n RC5 release?
