Not sure where you get that the kernel is identical. It is not like they compiled exactly the same source for each, there are differences. For one the Windows Phone 8 has to run Windows Phone 7 apps, so there are some differences there. Windows RT has some differences from Windows 8, they are built for different processors. There are enough core components that and app built for any one of them can be compiled to work with the others, but it doesn't just happen if the application is more complicated and uses components outside the core set.
