What do you want this application to do? Various example applications come with the SDK. For example, the S60 5th Edition SDK (and the earlier ones too, of course) comes with a "Hello world" example that you can import into Carbide.c++. It's located at <S60_SDK_installation_directory>\S60CppExamples\helloworldbasic.
Well it has an unsigned sis download available which you can sign to install on the device, it also has the entire source code so you can import it and build a sis out of it.
Are you facing any other issues..if yes what r they?
