Hi guys, Maybe one of you can clarify, if you're brave enough to test this, but can this be the real Rubyra1n? I found it simply by searching for 'rubyra1n.exe' in Google. Try it...?? http://www.mediafire.com/?wcb3umb17lhchgq I ran it and it looks like the real thing but I didn't connect my device. I'm not confident enough to try as I'm happy on 4.1jb and have no reason to risk it, but I'd be interested to hear whether or not it can offer untethered jb for 4.2.1... Any takers?
