I have both a Mac and Windows machine. Before I sold my jailbroken 4.3.3 iphone to get a 4S, I was using iOS5 semi-tethered. I used redsn0w to jailbreak iOS5. I did notice that older redsn0w versions were buggy on Windows and I had better experiences using redsn0w on my Mac than Windows. If I am not mistaken, as I don't have the 4 anymore, you can re-jailbreak (install Cydia is checked) and then boot tethered again, it might work. I had to do this a few times when I was dealing with earlier versions of redsn0w. Good luck
