Actually, the traffic metadata (email headers, browser user agent,
source and destination IPs, etc.) has long been fair game without a
warrant under Smith v. Maryland (1979), and is part of the provision
that supports lawful NSA data collection under the FISA Amendments Act
of 2008 and other law, in conjunction with telecommunication operators
like AT&T.
But that is getting far afield from this topic.
Again, I agree that there is no way in any practical or realistic
scenario in which AT&T is going to find out that any iPhone user is
tethering, especially if you stay under 5GB/month of data use.
However, the point still stands that it violates your terms of service
with AT&T, and it's clearly not what Apple or AT&T want you to be
doing as evidenced by the 3.1 update.
Mike, I appreciate what you're trying to do, here; I know it's
something that simply apparently "works" (and indeed it does), and
doesn't seem to be a "hack". But given the nature of this list, I
wanted to point out that there are other issues that should be
considered before deciding this is the way to go.

one either.
It is best to abide by the agreements put in place, there is no
doubt... this is offered just for testing incase your agency is
looking at some type of remote data access... we had a site with no
internet connectivity and they ended up buying the cricket mobile
cards until the cable could dropped.... the iPhone would have been
useful in this area.
At any rate, in an effort to keep honest people honest, I am going
to take that link down by midnight MST tonight... I do not want to
upset apple... if you need it for research - grab it while you can.

Here is one (of many) an easy ways to tell whether traffic is iPhone
generated or from an full-size computer. HTTP USER-AGENT strings
are sent as part of every web request and specify the browser and OS
you are using. Go to IPChicken.com<http://IPChicken.com> on your
phone and your laptop, and see the difference. You can spoof those
strings, but most don't. Someone running a router (in this case,
AT&T) can see this information trivially.
There are differences between technical barriers and legal/ToS
barriers. The bottom line here is to read your user agreement and
follow it, no matter what the technology allows. Any other actions
are taken at your own risk.

Trust me, there is NO WAY under 3.0 or 3.01 ATT can tell if you are
surfing through the iPhone or a tether. I could get into specifics
as to why, but I won't... but on that note, 3.1 changed that.
You can even take an ATT wireless network card, put your iPhone sim
card in it and surf through a mobile connection card... ATT makes no
changes from the iPhone to their regular remote APN.
I have four iphones like I said.. this one will stay 3.01 forever
unless ATT offers something comparable.

This is not supported by Apple or AT&T, and is a violation of AT&T's
terms of service (which has specific, discrete data plans for
tethering).
While it doesn't require *jailbreaking* the phone, it's still a hack,
as it replaces the devices carrier file with an unsupported one to
expose the tethering option.
The reason why tethering plans cost more is that it's far easier to
use significantly more data via a conventional computer than it is via
a handset, even a smartphone. While the jaded among us might say it's
just another way for a carrier to grab more money, AT&T has had
incredible difficulties keeping up with even the network demands of
the iPhone itself, which has been referred to by analysts as the
"Hummer of smartphones", because of the fact that iPhone users use
disproportionately more data services than other smartphone users.
This is because the iPhone makes it so easy; similarly, iPhone
tethering is ridiculously easy, and if it were "just enabled", AT&T's
network would quickly collapse under the onslaught, and any network
buildout to support such usage would result in unlimited data plans
being far more than $30/mo.
