Subject: AT&T to revoke unlimited data plans from some users Message-ID: <firstname.lastname@example.org> 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. ... http://www.wired.com/epicenter/2011/08/att-revoke-unlimited-data/ ***** Moderator's Note ***** 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? -- Barry Margolin, firstname.lastname@example.org Arlington, MA *** PLEASE post questions in newsgroups, not directly to me ***

Subject: Re: AT&T to revoke unlimited data plans from some users Message-ID: <CALtjCnLjxmnhS4QnFX3dTyqQj78pO=1LAOE20uDUSho_QEAF6Q@mail.gmail.com> 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. John -- John Mayson <firstname.lastname@example.org> Austin, Texas, USA

Subject: "splicing" into a fiber optic trunk Message-ID: <firstname.lastname@example.org> 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.
