Did you even read the OP's post?i find that jailbreak is doable for most firmwares, it's the unlocking that i believe has the dev-team screwed. always make sure that ultrasn0w works on that jailbreak before actually jailbreaking oh and make sure you always use pwanagetool because that will build a custom firmware, meaning it save an unlockable baseband.
I hope Comex and the rest don't waste a minute of their time on anything but 5.0. No point in losing our JBs on anything but that update. It's downgrade or wait from here on out.no one knows exactly when the untethered jailbreak will be out, some say when iOS 5 is released, which makes sense, im atleast kind of happy with my tethered jailbreak, heres the guide if anyone else wants the same
im sure comex will find another untethered
