Hi,
it's no harm to specify the ~ITSMOBILEDEVICEINCLUDE in SICF
it is usually used when you have the parameter
~sources itsmobile_a,itsmobile_b,itsmobile_c
and you want to use the Device Include from itsmobile_b or itsmobile_c services
Utkarsha is correct in that you need to specify the new Z_DEVINCLUDE in the actual HTML templates of the service
