For those of you keeping OS 3.0 for fear of breaking the jailbreak, fret not!; for it’s been confirmed that the current redsn0w and ultrasn0w utilities work on the 3.0.1 update. And patch it quickly because the SMS vulnerability which 3.0.1 fixes is a doozy. Yep, it’s a pain, but keep in mind you’ll have to jailbreak and unlock the phone after you update.
