1. Open a browser on your eDGe
2. Enter the following in the Address Bar and tap Go:

3. Once it's downloaded, tap the APK file and follow the prompts to install
Some notes:
- it appears the Amazon App Store is currently US-only
- some apps may not work on the Android 1.6 OS the eDGe currently has; unfortunately the app info doesn't indicate the version of Android required
