Like many other Nokia model smart phones, the Nokia N95 uses the Symbian operating system. In order for an application to work on a Symbian-based phone it must be signed. This signature is what confirms the authenticity of the application, ensuring that it is not malware or a virus. There might be instances, however, where you want to try out a beta application (meaning it's still in development) on your Nokia N95. Beta applications have not been certified by Nokia yet. To use an unsigned application on your phone, you must generate a developer certificate to digitally sign the application yourself.

2. Go to the Symbians Signed website (see Resources). Register to create a new account.
3. Log into your Symbians Signed account. Select "Open Signed" in the menu. Download the Developer Certificate Request Tool installer. Save the installer on a directory on the computer's hard drive.
4. Navigate to the directory location where you saved the installer. Right-click on the installer and select "Run as" from the shortcut menu.
