Thank you all for your help.

Followed the instructions and was able to download and install the Apps I wanted.

Apps successfully installed and working on my eDGe:
. Amazon
. eBay
. iHeart Radio
. Nook for Android
. Rhapsody (beta)

Next, I am going to follow the thread on converting a couple of them to full-screen.

I installed the Rhapsody (beta), but I could not get it to recognize my eDGe as an "mp3 player" so that I could transfer my albums to it. I guess because its a "beta".

Thank you again, everyone.
