Untethered Jailbreak for Windows is finally here.  It was announced by Redmondpie earlier.  Now iPhone4 with iOS 4.2.1 can start enjoying their holiday and festive season by jailbreaking their iGadgets.
What a lovely angpow this year with the new release by Chronic Dev Team.  It has been the long wait since the last jailbreak for window platform.  What I can say is MARVELOUS!
I am updating my iOS as this thesis is being written. Saw this announcement through rockmelt from twitter account.   Those that wishes to follow me may do so @semicyber on twitter.
For clear methods and guideline to jailbreak just read through from the link provided below or watch the video.  Don’t worry jailbreaking is not illegal and you won’t want to isolate fun from iPhone4 by jailbreaking??
