My problem: The more complicated applications (for example the Gui/Engine example by Nokia) disappear on the mobile phone after they are set up on the phone using a sis-packgage. You can’t find the startup icon.
Simpler application (with only one physical program module, The Hello World with menus) works just fine on the phone. Everything runs on the emulator.
My testing environment: C++ Builder 6.0 with Nokia mobile SDK 0.9. The phone is 3650 (I don’t know about the 1.2 SDK for the full C++ Builder 6.0. The SDK 2.0 is for Symbian 7, 3650 runs Symbian 6.1, I suppose).
