You can't upgrade from that version. You actually need to be at 1.13 or higher to upgrade yourself. It's technically possible from 1.11 but officially discouraged because of how the updates work and what gets installed with each one. You should call and arrange to have it sent in and upgraded when time permits. The EX1/3 firmware has been taken down from the US web sites and can only be legitimately obtained (i.e. from the U.S. Sony Sales company, not from Sony UK, Canada etc) by calling the tech support office and telling them that you are at 1.13 or higher (EX1) or 1.05 or higher.
