The big issue with getting a jailbroken/unlocked iPhone recently is that all the carrier unlocks weren't working for phones with firmware 3.1 on it, as that updated the baseband firmware to such a state that the normal unlock (different than the Jailbreak) couldn't unlock it. Well, turns out today is a sn0wday, with the jailbrak and unlock combined in once nice package. Link has details, also check out http://iphonejtag.blogspot.com for the announcement and features.

Yay freedom!
