Fonts in iOS. What am I missing?

How do you change the size of a font on a GUIText or GUI.Button? We should be able to do this to begin with, but text is almost microscopic on a retina display.

I try and change the font size of a GUIText and it tells me that I can only change the size of a dynamic font.
I install a dynamic font and it tells me that dynamic fonts are not supported on iOS??

Import the font at a different size.
