iPhone hacker, geohot, has released blackra1n RC2 for your enjoyment. It corrects a few small bugs from the first release and can be downloaded here.

•Fixed 3G issues
•Tethered jailbreak for 3.1 OOTB ipt 8GB and new 3GSes
•Fixed icy issues
•Both Windows and Mac
•If you used RC1 with success, no need to rerun
So nothing earth shattering but it is worth a mention and on the unlock side, geohot is not working on that but the Dev Teams MuscleNerd is. So rest be assured a iPhone 3GS unlock is being worked on, we just have to be patient.
