For those of you that are not on top of what’s happening in the iPhone community, the Dev Team, the preeminent group of iPhone hackers, just released Yellow Sn0w, a software unlocking tool that can be run directly from the iPhone.
Yellow Sn0w is ridiculously easy to use, assuming you’re already on a jailbroken iPhone. If you’re interested in unlocking your iPhone so it can run on any cellphone carrier, then hop over to my iPhone blog where I wrote a post about how to unlock the iPhone 3G.
