Using a developer's certificate to sign an unsigned Magic Keys Symbian app.
"Magic keys" is a Symbian application developed by "Leftop." Symbian is a type operating system used on some smartphones such as the Nokia 6650. The Magic Keys app is designed to remap the keys on a phone's keypad. As of January 2011, the Magic Keys application is still in the beta phase of development, meaning it's still being tested. Symbian based beta apps are not signed. To use a beta application such as Magic Keys on a Nokia 6650 cell phone, each user has to sign the app for themselves to confirm its authenticity because beta apps have yet to be certified by Nokia.
