Jailbreak and unlock iPhone OS 3.0.1 today

Those of you who abstained from updating your iPhones to OS 3.0.1 for the sake of keeping your device jailbroken and/or unlocked will be pleased to know you apparently have nothing to worry about. The iPhone Dev Team is reporting that the same versions of redsn0w and ultrasn0w that worked for OS 3.0 are fully compatible with the new software, albeit with the aid of a little more trickery than usual. To jailbreak, all you need to do is install the 3.0.1 software, fire up redsn0w, select the IPSW file for OS 3.0 (you still have that on your computer, don’t you?) and sit back while the magic happens. To take it one step further and soft unlock, just grab ultrasn0w through Cydia and you’ll be on your merry way. In case you’re wondering how this works, it all has to do with the fact that 3.0.1 is essentially a carbon copy of 3.0 with the only real difference being the code that patches up that nasty SMS exploit.
