Nope javispedro has said it "may" be possible, but he's not 100% sure until he has a N9 to test.
The hw's there, tis just the antenna config that may cause issues, working well in practice needs to be tested.
He's ruled-out the N950 as it doesn't have the right hw, let alone proper antenna config...

As for BT4.0, I was told by someone internal that it was actually very close to being done.
They told me what remained (cant recall OTTOMH) and suggested I file a enhancement request.
Been meaning to for a mth+ but I fear it'll be a waste of time, will prolly do it in a day or so, inc. the info I have.
