Thanks all for the responses..I guess I will have to depend on Wifi. Don't want to Jaqil break my iPhone..

I do have to agree that their choice of bluetooth protocol implementations is a bit... odd.

A2DP should be there; and likely is in some form, to be honest, but I am willing to bet that they were having performance issues. Apple does have a strong tendency to remove un-finished features to maintain a high degree of gloss / usability. It would not surprise me in the least if the audio quality and battery hit were too grave for Jobs, as it hurt the image of the device.

Someone else in here was spot on with OBEX and DUN/PAN I think... OBEX because they don't want you to be able to OBEX-push files to and from the device, probably because of the fundamentally locked-down nature of the system. DUN/PAN I can't really fathom entirely... to me it comes across as "curb features, simpler design" but I'm entirely unsure. It could easily have been as a toss to AT&T to allow the iPhone to fly on their network, but I still can't comprehend the decision... plenty of other phones support DUN/PAN and they seem to push the technology heavily.

Still, the iPhone only has token bluetooth support in my opinion, though it easily fullfills the primary goal: hands-free headset support. Basically required on any decent phone.

Also, I apologize if I'm amiss with any of this reasoning, I don't own an iPhone, my conclusions are simply from my readings and musings.

I wish I had enough faith in apple to think they didn't have A2DP because it 'wasn't ready,' but let us not forget - Apple wants you to use Apple stuff. They finally removed the proprietary headphone jack on the 3G iPhone - a MUSIC player, and it has a non-standard headphone jack. Nice one! I will happily bet money they didn't include A2DP because they'll be coming up with iWirelessHeadphones soon enough, and they will be the only ones that work with your iPhone. Apple would have loved to do that sooner, but it's hard to market a music device (iPod with a nonstandard jack). Once you add a phone, it gets a little easier.

As others have said, OBEX falls under the category of 'able to put information on the device without using iTunes' which is just not what they want you to do. DUN, yeah right - AT&T even says using the DUN feature in your phone is against their Terms of Service.

Anyway, it's a total shame, and one of the reasons I got the n810 in the first place. It's sad they don't play nice together.

Ok, there has been a new application in the iPhone app store called NetShare. I think it's 10 dollars but it allows you to use your iPhone as a modem. Though the app was taken down and put back up a few days ago (developers had to talk with Apple to argue its use as something other then tethering.. [I think usage as a proxy or something].

I heard about NetShare yesterday too. It's better than that, Laughing Man... Apple took it down, put it back up, and then took it down again, all without contacting the software developers. See: http://www.nullriver.com/

By the look of it, it will be made available in nations whos operators dont care if you have a tether plan or not...

But its yet an example of apple thinking that the world ends at the borders of usa...
