I rooted my NC using ManualNooter. As I now try to install apps but cannot because there is no file manager. I cannot install a file manager because I need one to install any app. i am able to download apps using Dropbox (using the browser) but cannot install them. There is a library app but when I click on the apk, it tells me that the format is not supported. How can I get around this without using the Google Market? I am not logged in and do not want to since I plan on selling the NC. Thanks.
