if you can’t wait, grab the pre-release - use the so called LSCM unwrapping method (when in face-select mode, press “U”>>LSCM). search the forums for a how-to (as i don’t remember the right link, else i’d post it )
for the lates testing builds, go here:
brief description of LSCM: basically you define “cutting” edges on your mesh (in edit mode, select vertices that make up edges, press CTRL+E). if you lay them out properly, the unwrapping method unfolds the geometry pretty nice. its easy to imagine (at least for characters and such) if you think of a (dead) animal. how and where would you cut it’s skin to have separate, unfolded pieces of leather? define those cuts in your geometry, and LSCM will do the rest.
hope that helps
