yes, it's a nice app, but it can't associate with every app, just the apps from its list
You are digging up and reading a thread that is a year old. Wiztiles was one of the first tile customization apps and it is free. There are plenty more available now. Why not take a look at them and see which one suits you best.
I studied the tile customizing apps from the marketplace, but I could not find none to change the tile of a named application (ex. "Speed Dial" app)
