Amazon has the full version of Docs to Go at half price ($7.49 instead of $15). You can't "load" the upgrade key until you've installed the "main version". My main version is part of the Acer bundle ... so Amazon doesn't see that I already have the main app. Without rooting ... Is there a way to uninstall the "Acer" Docs to Go main app so I can then dl and install the "Amazon" Docs to Go main app ... then 'install' the full key? Acer Iconia A500 ... no rooting, no mods, lots of free apps!
