Troubleshooting: .sis vs .sisx?
Whats the difference?
No difference to Symbian device, its just the filename.
Common: .sisx = signed version of unsigned .sis. But:
Nokia Qt SDK: .sis is already signed, no .sisx is created!
When not specifying own certificate: .sis is self-signed with
automatically generated certificate
Installation of self-signed apps not allowed by default on
some operator branded devices
Change: Application manager Installation settings
Software installation change from Signed only to All
