My phone is a landline and has no smileys. It has no sense of humor whatsoever.If you look at the smilies on your phone, the built in ones are similar in number and variety.
I don't like most of the modern smileys. They lack the character of those created by artists such as Millan, Viannen, Balaam, The Fool, Aiwan, and numerous others. I used to belong to a smiley forum that had a database of over 10,000 smileys, most of which were Invision-style, and we were constantly creating more. We have a few Invision smileys here. It's a tossup with some of them, whether I prefer the Invision style or The Fool's style (his are smaller and cuter).
