AT&T To Revoke Unlimited Data Plans From Jailbreaking iPhone Tetherers
By Casey Johnston
August 5, 2011
AT&T will begin revoking unlimited data plans from customers who
jailbreak their iPhones to use unauthorized tethering services, the
company confirmed to Boy Genius Report today.
AT&T's action applies to all customers tethering on the sly, whose
monthly bills will automatically have AT&T's 4GB tethering-approved
plan added to them if they continue to tether past a certain date.

For those of us not yet tethered to a digital fire hydrant, some
definitions might be in order.

Where in the article did it say that this is how these hackers did it?
I wouldn't be surprised if that's what they did, but there was no
confirmation of it.
I'm surprised that this works on a cellular network. Can't they
identify cellphones by their SIM cards?

Sure they can. But they can't identify the owner of the hand
that's holding the cellphone they've identified the SIM card in.

Speaking of tethering (i.e. sharing your phone's broadband connection
with other devices), can someone explain to me the justification for
charging extra for this?
I pay my provider $X for 2 GB of data per month. How does it cost
them more if I use this data with my laptop versus my phone? My phone
can only RX/TX bits so fast, so it's not like I'm hogging bandwidth.
I can't help but think it's just a way for them to make more money.
If there's a technical reason that I'm not understanding, I'd love to
hear it.

You just gave it: "it's ... a way for them to make more money." :-)

Subject: "splicing" into a fiber optic trunk
Message-ID: <j1p8ll$kel$1@reader1.panix.com>
Anyone familiar with, or can point to, a "how to"
in regards to splicing (term used loosely) into
a telecom fiber line?
It's a legit purpose...
We've got an actual _alternative_, as in second option, facilities
based telco near a site I'm helping spec. Actually three options..
there's the entrenched telco, there's a real local company
with its own physical plant, and there a cableco.
The building already has copper from all three, with individual
offices choosing which ones to use.
We'd love to get a fiber run into the complex.
The independent telco has a fiber run about 100 feet away.
We're just starting the discussion with them, but I'd
like to have enough info to be dangerous in the negotiations.
So... the key question is... can they "splice" into the
fiber that's just about next door, or do they have to
run a new line the distance to the CO.
for that matter, how do they physically do splicing
these days? would it be passive mirrors, or a Magic
Box [tm] that would get installed on the pole?
All info appreciated.
Thanks
