"The A2DP profile is introduced in AKU 2.0 of Windows Mobile - the same deliver vehicle for the Messaging and Security Feature Pack. Then - not only will you be able to get Push Email - but you'll be able to listen to your music without wires!"
I would consider Jason Langridge a pretty reputable source on what was to be officially included in AKU 2, and since the profile is in the QTek ROM, I think it's pretty safe to assume i-Mate took it out (As opposed to QTek put it in)
