Changing the "Select a page" label to the mobile menu

Hi there,

I'm trying to change the "Select a page" label from the mobile menu view, for a "Menu" label (as the web is in Spanish)

I've changed it from the simplecorp.info and the js/plugins/jquery.mobilemenu.min.js the two only instances that I've been able to find within the code.

Yet the menu keeps showing "Select a page" instead of "Menu"

What am I missing?

Thanks for your help, great theme
