Changing the font size of GUIText (on Unity iPhone)?

Hello, like the title says, I'm having a hard time changing the font size on a GUIText object, and normally in regular Unity when importing a font theres a size option in the importer somewhere, but in Unity iPhone that's nowhere to be found.. is there some way to do it through scripting?

Any help is appreciated,

Thanks! :)

Select the font and click the Settings... button.
