> As an example, at one point it apparently would simply refuse to start on the Droid X, despite running great on the original Droid I had to test it with, and the VM I set up to emulate the X. Without access to a physical Droid X, it couldn't be debugged. The app doesn't require anything from the hardware besides a GPS, so I was at a loss for what would cause this.

What ended up causing that problem?
