I am a member of a iPhone developer group, the iPhone "elite" (its a play on words, from the events that have happened on the osx86.hu IRC). We have some initial pages and a build of iPhuc. http://code.google.com/p/iphone-elite/
One of the new unlocks that has appeared in the past day for the iPhone, this does require some use of the terminal and instructions are only for AT&T iPhone users; at the moment there is no publicly released activation process for 1.1.1. The other unlock that has been mentioned around, the TIFF process, has not been publicly released yet.
