Geohot has tweeted saying that the jailbreak is easy but only helps those dumb enough to upgrade.
I hear rumors going around that the 3.1.3 jailbreak is hard. It isn't. But the only people it helps are those dumb enough to upgrade. Sorry.
These comments indicate that it's unlikely the BlackRa1n jailbreak will be upgraded to support the new firmware.
iPhone 3GS and iPod touch 3G users - please be very careful you do not upgrade. Most other users can still jailbreak using RedSn0w. See here for more information.
