Update iOS on Original iPhone

I have an un-activated Original iPhone that was replaced by my 3GS. I'd like to update the old model to iOS 3.1.3 (which, IIRC, was the last version to work on the Original iPhone) before I pass it on to someone else.
Can I just hook it up to iTunes and click on Restore to Default? I plan on using my G4 iMac running Tiger and iTunes 9 so as to not mess up the settings on my main iMac.

What is confusing you?
You can use the iphone as an ipod:

You CANNOT update or restore without the SIM in the iphone that was previously active or an active SIM.
From the article above:
"To continue using your original iPhone without active cellular service, leave the inactive SIM card in place. You will be able to use the iPhone as you would an iPod touch (Wi-Fi only, no cellular service) as long as you keep the SIM with which it was last used, even if you update or restore the operating system of the original iPhone."
