I only have cordless
phones in my house so I don't know if it will
work anyway
You can't use a wireless, i.e. cell phone, for the upgrade. Your cordless phone plugs into the telephone company's lines, which is fine for upgrading.
OT: By the way, you should *always* have a real, corded phone available in your house.
