I'm trying to JB using redsn0w, as this seems to be the only option if you have an iPhone 4 on 6.1.3
Everything goes smoothly, but after a while i get this screen:
Missing Keys.plist data for this build
I jailbroke my iphone 4 6.1.3 with redsnow. Just open, extras, select ipsw, 6.0, then hit jailbreak, follow thru, when done an phone turns on, restart redsnow, extras, select ipsw, 6.0 again then boot tethered and youll be done.
