If you've hacked your Nokia you can install unsigned programs by simply dropping a modified installer into your phone's system folder. The modified installer doesn't bother with certificates or signatures, but simply installs anything you throw at it without asking all kinds of annoying questions like the default installer does.
The list of phones that can use the modified .sis installer has grown a bit with the release of a SIS Installer Mod for the Nokia E50, E61, 3250, and 5500.
