Many of these market places have their own market place app, as does AppLibs. I saw the prominent link on the left side of the page. Unfortunately, the AppLibs app doesn't install on the eDGe.
The second strategy in these cases is to do a Google search for "<app name> APK", in this case "PDF Utility APK". As it turns out, this search doesn't provide useful results (note that the AppLibs page misspells "Utility", too).
At this point you have to get creative. Ultimately, a Google search for (note my use of quotes):
"PDF Utility Lite" APK
gives you good links, including
http://handheld.softpedia.com/progDo...ad-105564.html (I think it's 4.0, though, not 4.1). I downloaded and installed the app, and it works full screen. I didn't test out its actual functions, though.
Have fun!
