I'm not seeing the "Show me more/less" tiles option on the icon? It should be in the "start + theme" menu, correct?
I don't believe it is an option on the Icon to use less than the 3 columns, since the Icon is a 5" phone.
Hehe.. I took these pics. They were screenshots from another device, placed on the Lumia Icon. If you look closely, you might be able to see a smudge on the lower right corner to hide the three dots from the Gallery
So the Icon does not have the option to go from three columns to two. But the official Windows Phone twitter handle still posts this. I don't dislike having three columns. In fact, I probably prefer three columns to two. But it'd still be nice to have options.
