They decided the name Smith Micro needed to be at the top of the interface. Also, apparently  what people REALLY wanted were two more characters, male and female, that were even fuglier than anything prior, by a great degree of magnitude. ;-)

Well, maybe they added some free ringtones in there somewhere, although I have yet to find them.
