Sorry about the code... What I don't like about Vito, and all of the others I have seen, is that it doesn't "replace" sms, it is just another program that uses WM sms. I tried Vito but seemed to end up using WM sms all of the time because my interface always opened it. Unless you use Fun Contact, when you goto a contact and hit "Send Text Message", it opens WM sms.
By the way, a little more research came up with another PPC version of A.SMS..
