Symbian Signed For Stub SIS files
If your application is being included in a firmware build it may be desirable for the Phone Manufacturer to include your stub file in the firmware too. Stub SIS files do not require any capabilities and do not need to be Symbian Signed if they are to be included in the ROM. If, however, your application is being shipped on a memory card it may be required to be Symbian Signed. In this case the SIS file should be submitted in the standard way to be Symbian Signed as a “Passive Content” file type. The main application associated with the stub file should be Symbian Signed before the stub file is.
