@planetbeing has tweeted that the public release seems to be vulnerable to all the jailbreak exploits they are planning on using, so that is very good news.
It appears that those who want to, can at least prepare to update to 6.1. However, potential jailbreakers should note that any update to 6.1 must NOT use the OTA (over the air) method. Use the full iTunes update or restore operation (whichever suits your needs).
Personally, I'll be waiting until the JB is released since it will support the current public version of IOS (and therefore, there is no rush at this time).
