I can't find anything for the i8910...
the I8150 / SGH-i900 / SCH-i910 are there...
e.g.
http://certification.dlna.org/certs/REG20225883.pdf
The i8910 is not under Samsung's entries ...
might this explain something?!
I wonder what DLNA certification actually means in practicality? as opposed being a piece of paper...
