Just a quick post to remind every unlocker and jailbreaker out there that if you can’t live without your jailbroken and/or unlocked iPhone, you should not update to 3.0.

Updating to 3.0 will simply prevent you from jailbreaking or unlocking your iPhone, no matter if it is a 1st gen or iPhone 3G.

My advice to you: wait a few days for the Dev Team to release a new jailbreak for 3.0 and for UltraSn0w (the new app that will unlock your iPhone) to be released.
