An APK is an application you download onto your computer - then move it to your phone using Astro (free on market) to install it. Then it's just like a normal program you got off the market.
You don't need to root or anything to use these since the developers make them specifically for anyone to use.

So hopefully 2.1 will add more screens. But if not, download the APK form Android Central? Whats an APK tho?
