I'm running iOS 5.01 on a iPhone 4. Just installed 5.01 as a new phone and restored from backup. I'm on Win XP and while running redsn0w, it gets past "Exploiting w/ Limera1n" and starts "Uploading Fist Stage". At this point, I get a Windows dialog box that says "redsn0w encountered a problem and needs to close". I'm able to then reboot the phone and it's looks to be in the same state as it was prior to running redsn0w (i.e. not JB). I've tried it several times and it can't get past that. It's odd, since previous to this, I was running 5.0 with a tethered JB. Is anyone else seeing this problem?
