In the browser on your eDGe, type the following in the address bar at the top of the browser: http://www.mediafire.com/?4or7i6bnoqzor36 and click the Go button. When the page appears you should see a "Click here to Download" link (you may need to wait a couple of seconds for the page to refresh with the downlaod link). Tap that and you should see it download, etc.

If this doesn't work, then you'll need to do that on your PC and email yourself the APK (or put it on a memory stick).
