The 4.0.1 firmware is out now, but Apple is STILL signing 4.0 for a LIMITED time. If you have not got 4.0 on file then now is the time to do so. This may only last for a few more minutes, or hours at the most.
And as a side note, if you are dependent on an iPhone 4 unlock DO NOT upgrade to 4.0.1 until we know whether it contains a baseband update or not. Jailbreakers don't have much to worry about as long as they have 4.0 on file.
