Subject: iPhone jailbreaking (and all cell phone unlocking) made legal
Message-ID: <1C.81.03317.8303E4C4@hrndva-omtalb.mail.rr.com>
The FCC has decided to allow (with some restrictions - see whole
article) the Smartphones to be legally "jailbroken" - unlocking of a
Smartphone to be operated on another carriers system and in the case
of the Apple iPhone, be able to run apps (applications) which Apple
has not approved.
The complete article is found at:
http://news.yahoo.com/s/ytech_wguy/ytech_wguy_tc3236
Also note in the article some additional "digital rights" changes
which are almost tantamount (according to the article) to allowing
the individual purchaser of a DVD to "legally" make a copy of it -
the actual permission was granted to Professors, students and
documentary filmmakers for non-commercial purposes to break the
copy-protection measures on DVD's. But isn't everyone a "student" of
the art of film viewing?

This has nothing whatsoever to do with the FCC.* It's actually from
the copyright office, via the Librarian of Congress since the
copyright office is part of the LoC.
There is a part of the copyright law against breaking software access
controls which has a bunch of exceptions, with the details of the
exceptions to be interpreted by the copyright office. This recent
decision says that jailbreaking your phone for the purpose of
connecting to another legitimate network is one of the exceptions.
Cracking DVDs to use snippets in news reports is another exception.
It also says you can crack videogames to test for security flaws,
crack dongle code if nobody sells the dongle any more, and crack some
ebooks for use with screen readers.
The actual realease is here: http://www.copyright.gov/1201/
As others have noted, this does not affect any contracts you may have
agreed to when you activated your iPhone.

In the case of a split, such as when southern New Jersey created 856
out of 609, the people in 609 kept the same phone number they always
had. The people in the 856 section had the new area code, but the
individual phone number didn't change.
In the context of this discussion, note that splits also have an
overlap period. That is, during the overlap time one could dial 609
or 856 to reach an 856 number. This gives people time to get used to
the new dialing arrangement.

It's still a horror scenario which I am glad that [we] were able
to avoid.

The federal network agency[1] now imposes a minimum length for newly
assigned numbers, so that even connections in a tiny mountain village
with 50 houses get six digit numbers in the four digit area code.
Assigned numbers, however, stay that way[2] until the owner[3] cancels
the contract or moves away[4].

There are exeptions, however, for numbers which are likely to get a
high number of calls. For example, the new Hotline of 1und1, one of
the largest ISPs in Gemany, is located in the Area Code of Karlsruhe,
and has only four digits, while other newly assigned numbers in
Karlsruhe have seven or eight digits.
Additionally, we handle PBXes a little different here. Dependent on
the number of lines (I think that you would say, the width of the
trunk) to the PBX, the subscriber gets a base number of a certain
length and can add on her own extension numbers ad discretion.
For example[2], with 10 lines in an area code which has seven-digits
local numbers, you get the local number divided in xxxxyzz, with xxxx
being your prefix, y as 0, 1, 2 or 3, and zz to be chosen at your
discrection. The next subscriber with ten lines may get your xxxx,
with y as 4, 5, 6 or 7, giving both subscribers 400 numbers to
individually assign.

By "experts" I mean the people who engineer and/or research things and
actually know about the subject, not the bean-counters, political players
or PR hacks that decide too many things these days.
The "experts" I refer to try to do things despite the efforts of those I
just mentioned.

Of course. But that's still significantly different from what we're

This is true. But what's a person going to do? Given enough time to crack,
no wireless is totally secure. For that matter, no EMF is totally secure. I
once read that intelligence agencies can intercept room sounds by bouncing
lasers off the windows, since windows bend ever so slightly to sound waves.

Here's another one --
Consider a microwave cavity with 5 rigid sides whose 6th side is
a metalized membrane. Cavities resonate at a given frequency, and
when sound impinges the membrane the cavity's resonant frequency
is modulated. If the cavity is a part of a transmitter which is
powered by DC rectified from a local AM radio station's signal
and the assembly is placed in a brick which is then used in the
construction of, say, a building, one has a self-powered spying
device. This device really works -- I used to work for the
GTE Electronics Defense Labs in Mountain View CA (formerly it
was Sylvania Electronic Systems - West) designing and building
microwave solid state devices back in the 1960s. The stories I
could tell ...
:-)
***** Moderator's Note *****
One of the Soviet's greatest intelligence triumphs during the cold war
was their placement of a listening device in the American Ambassador's
office in the American embassy at Moscow.
It was a passive device, not requiring any power: they constructed a
very pretty copy of the American State Department seal, and placed a
microwave cavity inside it, hoping (as turned out to be the case) that
it would be placed in an important and secret room once presented to
the Ambassador. The Soviets then "powered" the cavity by beaming a
microwave transmitter through the wall into the cavity, and recovered
the signal with a receiver on the same path. The voices in the room
caused the cavity to vibrate, thus amplitude modulating the received
signal because the sound preasure waves de-tuned the cavity.

The above reference is extremely interesting* and explains what he
did. Quoting a part of it below:
"I had made lots of tests on telephone lines. These were pretty lousy
lines. Some of them ran on posts set in the ground used to keep out
cattle. Therefore the telephone lines had propagation characteristics
that were very different from one another. There were two things one
really could not predict - the bandwidth and the phase response. I
discovered, simply by messing around, that if I arbitrarily picked
something like 2 kilohertz as the upper end of what a reasonable
telephone line would do, and put a simple low-pass filter on the modem
output, the phase of the filter would roll off gently before the
signal encountered the severe phase distortion caused by the telephone
line itself. The result was that this line could be pinged and a
fairly representative pulse would be obtained at the end. The detector
I used was a very simple amplitude detector, a diode and a capacitor.
Of course there was amplification in between and there was digital
stuff that somehow synchronized with what was coming off the radar.
At the time Bell Labs had great men working on this, and they said if
one drives a telephone line over 600 bits per second, one has arrived
at the end of the flat earth, and you've had it. With my simple device
I did 1800 bits per second consistently."
As I understand it, back then long distance telephone lines were of
poor quality (open wire) and as a result modem speed was limited. Mr.
Rosen invented a circuit (as described above) that would be able to
push higher speeds over the phone line despite the distortion; that
is, his modem ignored the distortion. (I don't understand about
"phase roll off" but that's what apparently did the trick.)
I wonder how business people felt making toll telephone calls--which
were very expensive back then--over a lousy line. I suspect letters
and telegrams were major media until the telephone network improved.
(When I first made toll calls in the early 1960s I remember the lines
had a slight 'white noise' in the background--you heard it come on
when the connection was made--but the conversation was certainly
comfortable and adequate. I don't know how it was in the 1950s.)
Well into the 1980s long distance directory assistance (NPA+555-1212)
had lousy connections--very bad echo. But I guess they figured for a
free call they'd route it over their 'cheap' trunks. I don't know if
they even still offer that service--they certainly charge for it if
so. Anyway, they now advertise that 411 has national listings (for a
fee, of course).
*It gives his life story and his education and training.
***** Moderator's Note *****
The lines weren't "lousy" when used for voice: the problem with data
transmission is that it is subject to interfernece and distortion
which humans don't perceive. Normal phone calls sounded, well, "normal".
As for the "white noise" you heard on long-distance circuits, it was
added deliberatly. The "L" carrier was so quiet compared to older
methods that many subscribers would abandon calls because they thought
the other person had hung up, so noise generators were added to supply
the reassuring susurrus we all came to associate with "normal"
long-distance lines. It wasn't until Sprint, which didn't want to go
to the trouble of retrofitting the fiber network to sound like Ma
Bell's, launched it's "Pin Drop" campaign that public expectations of
long-distance circuit "sound" changed to what we expect now, namely
"nothing".

It's probably worth mentioning that the "sequential decoder" shown in
the Washington Post, of which the original photo is hanging on the
wall in the room in which I'm writing this, was a major contribution
that my dad, along with Claude Shannon (left) and my dad's long time
colleague and friend Jack Wozencraft, (right) made to the modern
technology landscape. The project did the fundamental work of what
has become known as digital signal processing. That's my dad in the
center of the photo, looking justifiably very proud of what they had
done.
Thanks for your interest in my dad's work.

Hang on, if the "reception" problems are in fact the phone receiving
signals then there may well be a direct correlation to the transmission
capabilities of the device, but there may not.
In any case, in real-life usage the source/sink that the phone connects to
is (usually) a long way away from the device and since signal reflections
etc are also a constant factor in real-life usage, then the only valid
tests should use these as well.
It would seem bogus to me to draw any conclusion from tests not reflecting
the actual conditions the phone will be used in - and not many of us would
use them in a lab or anechoic chamber.

Because they are sufficiently thickly populated that they can pay their
own way through their phone/broadband bills. Same as with subsidized
phone lines for rural areas for many decades.

One example mentioned in a Bell System publication--probably the Bell
Labs Record and said to be the first attempt to do this--was when the
Wisconsin National Guard went to summer camp in, I believe, Washington
state. All the soldiers headed for the phones in the evening to call
home, and backing up all HU routes to first, then backing up into the
Sacramento Sectional (?) center and degrading service all along the
Pacific coast.
Someone had the idea of, after a certain hour in the evening, making
White Plains the first choice after the HU direct trunks (not many of
those from Washington state to Milwaukee). By that time traffic was
way down to and from the East, so Seattle (or wherever the center
was)-White Plains trunks were very lightly loaded. Same thing for the
White Plains-Milwaukee direct trunks, and also the White Plains-Norway
direct trunks that would be the final route from White Plains to
Milwaukee.
Yes, changing the punched metal cards. It pretty well solved the problem,
and similar changes became almost routine for special events.

While we're on the subject of modem history, the following article in
the Western Union Technical Review describes FSK technology of the
early 1960s, including technical details on transmission
characteristics. How much of that stuff do we take for granted wiith
today's technology running at much higher speeds? [click next/
