I can't find anything for the i8910...
the I8150 / SGH-i900 / SCH-i910 are there...
e.g.

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...

mmm... a DLNA certificate has appeared for the S8000!

but there's nowt for the i8910 as far as i can see.

notice the AAC inferences in the above doc. i wonder what Stall means in the above certificate. time to do some more digging...
