Nope, not really. You could install the 2.1 multimedia dock, but that requires being rooted. You could also buy the Bedside app ... my personal favorite. Last but not least, you could root your phone, then go into the app and edit the PNG files. But that's a long way around the horn just for one silly app that you don't use very often.
OK, I lied. There is one last option ... but I'm not sure you're ready for it.
