So apparently there's NO FEE for getting added onto the standby list if you arrived on a connecting flight. Source: I just did it and the agent told me there's no fee as long as you arrive on a previous connecting flight.
(I have no status with united, I rarely fly with them and have like no miles or anything.)
Thanks everybody for their input.

Officially it depends on your status. Here are the rules: https://www.united.com/web/en-US/content/reservations/samedaychange.aspx
This being said, you can always ask. If your original flight is oversold or if the expect a large rebooking crowd because of an earlier delay and there are plenty of open seats on your original flight, they will probably take you.
