Just be careful, before you update, you must know that if you’re baseband will be upgraded, so your phone will be locked again. Until the dev-team release a new tool and unlock, you’re phone will be locked, and maybe “un-jailbreakable”.
But if you should update, before you do, open up Cydia, and follow the steps to have your ECID SHSH on file. If done successfully, a text will appear on the very top of the Cydia main page : “This iPhone 3G/S has an ECID SHSH on file”.
Doing this will possible help in jailbreaking the 3.1 OS.
Good luck!
