If you want fast data service in the USA then there is zero point in unlocking the iPhone. T-Mobile, the only other GSM-based provided in the USA, uses different frequency bands for its data than AT&T, so the best you will be able to do with data on an unlocked iPhone, presumably with T-Mobile, is EDGE data.
Demand. To someone selling an unlocked iPhone, you are listing out their wholesale cost. Of course, they will want to make a profit. On top of that, there seems to be a market for these and as there aren't a lot available, expect a fair cost to be about 25% to 50% more than that. I have an unlocked first generation I use as an iPod from back when Apple sold them refurbished in their store. If they ever pick that practice up, expect the prices to drop drastically.
It would appear that a Nissan Z car would be the upper limit.

I’m so glad you posted this. I’ve been contemplating this very same thing. I’d like to get an iPhone, but the service for AT&T is so horrific, I’m hesitant. I don’t know much about this “unlocked” option, so I’m eager to read what’s posted.
If you get a mywifi from Verizon, skype for the iphone, you can use the iPhone on the verizon network with skype for about 60 bucks a month plus the skype fees. You will get better coverage on the Verizon network as the iPhone has completely killed the AT&T cell network. Not sure if the Droid will have the same affect on Verizon, but don’t be surprised.
I heard that if you have an iphone like that, it might turn into a brick when apple sends out another update.
I want internet access for my laptop. I understand an iPhone 'jailbrkn' will work on other carriers.
Anybody have experience with this?
Why not just get a MyTouch, or a G1? Why are you so set on the iPhone?
