I'm just getting into app development, and cannot get the virtual device working on my computer (and it would seem that nobody can tell me why). I am, therefore, trying to install stuff I've written (so far, just Hello World, but I have other things in mind, too) from the SDcard, but the phone tells me that *MY* app is from an untrusted source, and cannot be installed. I trust myself. How do I bypass this insanity? Thanks.
