How to make the Wolfram Alpha Android App's keyboard the default one for the device?

I am an owner of the Samsung Epic, and while I was on Android 2.1, my default keyboard for the device was similar to the Wolfram Alpha's keyboard. I don't know how I got the keyboards to change in the first place, I just noticed one day that I had a awesome, new keyboard that made me completely forget about the slide out qwerty keyboard half of my phone. I recently upgraded to 2.2 and am now stuck with the awful factory keyboard that vibrates upon finger contact. Needless to say, I want my awesome, sexy keyboard that is actually enjoyable to type on back. If anyone has heard of anything like this happening before, I would love to figure out how I managed to get this awesome, wolfram-esque keyboard, rather than the stock one with ugly, and small buttons. Thank you for any help you can offer..
