Got word that the SharePort app will not work, but D-Link does not mention shareport on the box, web, or datasheet (in the US). What brochure did you see it in? Can you link it?
Any DLNA app that allows remote streaming should work. Usually you have to enter the WAN IP address (or use DDNS) and password.
I will do more testing with 3rd party apps since I do not know of any D-Link DLNA mobile apps.
