That I did not know, can you point to the doco which proves that the N9 uses this chipset? How would one access this protocol support, does the OS already support it, is it merely disabled?
This whole paragraph is ambiguous to me. Additional hw support for what? What's the UICC? Can you please clarify what you're saying here.
But what you're suggesting it seems, is that one just adds a SE*, & the SWP/NFC built into the N9's NFC chipset is used. Please correct me if I'm misunderstanding you. *via SIM most likely but possibly other options.
