For upper level executives as soon as you resign you're escorted out the door by security and you're not allowed to touch anything. The level of access you had was so high that they don't want you learning anything more about the company's plans and want you out asap.
I've been around some companies where any IT worker who gives 2 week notice is escorted immediately out of the building. It is not unusual for 2 weeks to not be needed or wanted.
Or Yahoo 360. What? It never launched?
Well, she could do it on Yahoo Mash. Huh? Got shut down?
Or she could post a link on Yahoo Buzz. What's that? Also dead?
Crud, maybe she could post it to facebook.
California is an "at will" state so she's under no obligation to give Google any notice if she intends to quit, just as Google doesn't have to give her any notice if they intend to get rid of her.

I doubt anyone cared that she resigned by phone.
