Are you talking about N810 or N800? Nokia doesn't even claim the N800 will support it, so that post is irrelevant.

Anyways, you come here to a free user support forum screaming and complaining. There are people here that can help you. If you don't like your product, send your complaint to Nokia.

An internet tablet is a lot more like a computer than a cell phone. You really are expected to be able to install software and follow some additional directions. Heck, even Windows 98 used to require you install additional drivers to get USB working. I'm sorry if that's not what you expected, but Nokia has all the appropriate disclaimers about software compatibility. The hardware is compatible.

I originally bought my A2DP headset to work with my Palm T|X. It worked, but it actually required that I pay for additional software (Softick AudioGateway, works great on palm BTW). Your N810 can be made to work with BT stereo headsets and it can be done for FREE.
