title: How to get System Installer on Tablet to accept Unsigned App
body: <p>I am in dev mode and have no ADB access to android 2.1 tablet.  I want to just transfer quickly unsigned app to downloads and install.  However installer always says Application not installed without giving reason. So I need to know how to get installer to accept an unsigned app. signed app installs fine, and I do have Unknown Sources Checked under applications.</p>
