Holy cow! a WiMAX edition having HSP disabled... I've been wondering about this; if it had been stated that this case was a WiMAX, I overlooked it until now. And now I guess we have an explanation on why.

Does make me wonder about Nokia's spec page, though; it still claims HSP support. Lies?

No, my bad. The profiles list on the N810W page actually has a null element where HSP is on the N810 page.
