They may all be at&t today, but quite possibly current subscribers
who originally began with one of the two companies named will still
have the same SMS email addresses as when their service began.
Certainly the analogous address-domain retention holds for the
email addresses of folks originally using PacBell, SNET, SWBell,
SBCGlobal, et al., as ISPs. There'd have been far too much
user-name clobbering had they all gotten converted to *@att.net
from their original *@pacbell.net, *@snet.net, etc. addresses.
But don't quote me -- I'm just hazarding a guess here :-) .
Cheers, then, and a large grain of salt, -- tlvp

iWatch: Is your phone spying on you?

CRIMINALS using the Apple iPhone may be unwittingly providing police with
a wealth of information that could be used against them.
As the communications device grows in popularity, technology experts and
US law enforcement agencies are stepping up research into their potential
for forensics investigators.
While police have already been able to track criminals by locating their
position via conventional mobile phone towers, the iPhones offer far more
information, according to experts.
''There are a lot of security issues in the design of the iPhone that lend
themselves to retaining more personal information than any other device,''
said Jonathan Zdziarski, a former computer hacker who now teaches US law
enforcers how to retrieve data from mobile phones.
''These devices organise people's lives and, if you're doing something
criminal, something about it is going to go through that phone.''
Apple has sold more than 50 million iPhones since the product was launched
Mr Zdziarski said he suspected that security had been neglected on the
iPhone as it had been intended as a consumer product rather than a
business one like rivals such as the BlackBerry.
An example was the iPhone's keyboard logging cache, which was designed to
correct spelling but meant that an expert could retrieve anything typed on
the keyboard over the past three to 12 months, he said.
In addition, every time an iPhone's internal mapping system is closed
down, the device snaps a screenshot of the phone's last position and
stores it. Investigators could access ''several hundred'' such images from
the iPhone and so establish its user's whereabouts at certain times, he
iPhone photos include ''geotags'' so that, if posted online, they indicate
where a picture was taken and the serial number of the phone that took it.

The people at Verizon Wireless expect lines at their stores next
Thursday, like the ones Apple Inc. had last month when it debuted the
new iPhone. It seems hard to believe; most people don't get that
excited over a new cellphone unless Apple chieftain Steve Jobs tells
Verizon is expecting its own brand of excitement for the new Droid X,
which comes from stodgy old Motorola Inc. Motorola delivered one of
last year's biggest hits, the original Droid. Based on Google Inc.'s
Android operating system, the Droid became a legitimate rival to
The Droid X, which goes on sale July 15, is even better, but will
carry the same price: $200 with a $100 rebate and a two-year service
The original Droid's worst flaw was its wretched physical keyboard.
The Droid X gives up on the concept; as with an iPhone, you type by
touching an on-screen virtual keyboard.
The lack of a hard keyboard makes the Droid X luxuriously lean. Its
structure is thickened only along the top, where Motorola has
installed an 8-megapixel camera with dual LED flashbulbs.
The same camera also shoots good 720p, high-resolution video.
But I wish Motorola had added a front-facing camera for videoconferencing.
The virtual keyboard comes with Swype, a program that lets you type
by dragging your finger instead of poking at the screen. To type a
word, touch the first letter, then drag your finger to the next, and
so on till you're done. Somehow Swype figures out the word, getting
it right about 98 percent of the time. It's almost creepy how well it

It has it's plusses and minuses. On the plus side, forcing people who
want Usenet to actively seek out a Usenet service provider has hugely
reduced what used to be the AOL crowd and the freshman fall crush.
On the minus side, a great deal of Usenet's value could be derived from
the network effect. That is, the more participants, the more value.
Unfortunately, the noise increased at a far greater rate than the signal.
The secondary loss was to Usenet redundancy and anonymity. When there
were thousands upon thousands of Usenet servers, all interconnected, the
loss of any one server was inconsequential. Now days, if Giganews,
Newsguy or even Google Groups dropped out, there would be a noticeable loss.
Couple that with how much easier it is for a "bad" government to
identify and closely monitor the point of entry for a particular poster...

I went to the link provided and the list of company names and
addresses appears to be really old. Sprint PCS, Cingular Wireless,
and AT&T PCS, haven't existed in years!

As I point out this appears to be an old list with the accuracy of it
questioned (at least by me.)

Subject: July 11th in History: 1948 Media PA #5XB, 1965 FL 305/904 NPA Split
I had mentioned in previous postings about how this year, 2010, is the
45th Anniversary of the very first #1ESS switch being cut-in to full
public PSTN/NANP service (as opposed to "experimental only", i.e., the
Morris IL ECO of 1960-62) at Succasunna NJ on Sunday 30-May-1965, and I
had also mentioned that the Florida 305/904 Area Code Split took effect
as a FLASH-CUT also that year, on Sunday 11-July-1965 at 2:01am EDT.
And I had also mentioned the fact that calendar year 2010 is identical
to calendar year 1965 as far as how the dates fall on particular
days-of-the-week. This year, 2010, follows 1965, in that 30-May and
11-July are both Sundays, in both years.
ALSO, 2010 is the 62nd Anniversary of the very first #5XB switch being
cut-in to full public PSTN/NANP service (as opposed to experimental
"only"), also on Sunday 11-July-1948. Note that both the 305/904 Florida
NPA Split and the first #5XB being cut-in at Media PA both happened on
July 11th in their respective years, and both were on a Sunday, so even
1948 has the same day-of-week "mapping" as does 1965 and 2010.
Regarding the first #1ESS in Succasunna NJ, I had mentioned in my
earlier posting that I was unsure if it replaced a SXS office or a
#5XB office. I tend to think that it replaced an earlier Step-by-Step
(SXS) office. I did some digging up of info from google searches, and
there was a reference that AT&T/WECO/Labs worked with NJ Bell for the
cut-in of this very first #1ESS to be installed in a town that had
been served by a (roughly) 4000-line SXS switch. And since the first
#5XB office in Media PA was only installed 17 years ago, I doubt that
anything less than 17 years old (i.e., a #5XB) would have been in
service at Succasunna NJ, only to be pulled from service to be replaced
with the very first #1ESS.
As for the #5XB in Media PA, a suburb of Philadelphia PA, it is likely
that it replaced a previously existing common-battery manual central
office. The suburbs of Philadelphia had mostly been manual -- Panel had
NOT yet extended into those suburbs. The first #1XB office was only
ten years old, first being installed in Brooklyn NY in 1938. It seems
unlikely that AT&T/Western/Labs and Bell of Pennsylvania would have
pulled a #1XB that was only ten years old to replace it with the first
Englewood/Teaneck NJ was able to dial their calls to Media PA as part
of the Philadelphia PA Metro area (215) with the first public use of
(limited) DDD (Direct Distance Dialing) effective November 1951, even
though it would be another 2-3 years before AT&T/Bell would actually
begin referring to customer "nationwide" long distance dialing as "DDD".
The 1951 customer instruction booklet only lists the TOWN name of Media
under Philadelphia and vicinity. It does NOT indicate the particular
NNX code -- or rather 2L EXchange NAme (plus 3rd-digit) for Media PA,
which would probably have been "LOwell 6-" (see below).
The "ratecenter" name for Media PA is officially known as "Philadelphia
Suburban Zone #12". The c.o.switch eventually had MEDIPAMEMG0 for its
CLLI code, the -MG(x) extension for "Marker Group", which was the code
extension used for Crossbar offices providing "local" end-office
services or functions.
It appears that the #5XB was still in service at Media PA as late as
1985. By 1990/91, Media PA was being served by a #5ESS (digital),
MEDIPAMEDS0. It does NOT seem that Media PA had any interim period of
being served by a #1ESS or #1AESS (non-digital), but was cutover from
#5XB directly to a digital ESS, the #5ESS, sometime after 1985 and
before 1991, but I don't have the exact date/year of that cutover.
The original 2L-5N "name" would most likely have been "LOwell 6-".
There was a new 215-565 added before 1974 (I do not have the year),
but it seems that 215-565 was added AFTER 7D ANC (All Number Calling)
format started to replace the 2L-5N "name" format. New office codes
would not have been "officially" referred to by 2L-5N, although since
both 565 and 566/LO.6 are both 56x codes in the same switch, one "could"
unofficially refer to 565 as "LOwell 5-". Later 215-NNX codes were added
later on, and the town of Media PA also fell on the new/split side of
the 215/610 area code split of 1994. VeriZon/BA/B-Pa also has a new
484-NXX code added since 484 had overlaid 610 back in 1999. The
ratecenter of Media PA/Philadelphia Suburban Zone #12 also has other
610-NXX and 484-NXX codes "default" assigned to wireless and CLECs as
I don't know when the last #5XB (or any other manufacturer's crossbar)
in the NANP/DDD network was replaced with (digital) ESS, but it would
have been by the late 1990s-era. The last "known" US/Canada SXS office
was in Nantes PQ Canada, replaced with a DMS-10 in 2002. The last Panel
offices were being pulled from service in the late 1970s or maybe even
as late as 1982, I don't remember the "exact" date (year) when the last
"known" Panel office was removed from the PSTN/NANP/DDD network. But
there are still roughly 60 remaining #1AESS offices in the PSTN/NANP/DDD
network as I had mentioned in postings earlier this year.
VZ/BA/C&P has three of them, one each in:
Baltimore MD, Richmond VA, Norfolk VA.
at&t ILEC has the rest of them -- a handful in Michigan Bell (four of
them to be replaced with digital sometime this year or next year), two
in Illinois Bell in Chicago Metro, and several in Southern/South Central
Bell and Southwestern Bell, concentrated in certain specific metro
Other than the four known replacements this year or next year in
Michigan, I have no idea when at&t or VZ intends on replacing the other
remaining 1As. There will still be a few in Michigan even after the
four currently known replacements.
But as mentioned in my previous posting, Succasunna NJ #1ESS (which
appears to have never been upgraded to a #1AESS) was replaced with a
#5ESS in September 1991.
ANYHOW, Sunday 11-July-2010 is the 45th Anniversary of the Florida
305/904 Area Code split in 1965, and it will also be the 62nd Anniversary
of the very first public network use of #5XB cut-in at Media PA in 1948.
11-July-1948, 1965, and even 2010 also ALL0 happen to be on a SUNDAY as

Philadelphia was the last place to use exchange names, finally
abandoning them for ANC in 1980. To this day it is not unusual to
find a business with stationery or a sign referring to its telephone
number by 2L-5N. Some forms mailed out by Phila govt still have MU 6-
instead of 686.
However, for new exchanges, they used numbers beginning in the 1960s.
This would be for either one of an existing 2L series or a whole new
NNX. That is, when BAldwin (22.) needed another exchange in the
1960s, it was called 221. Ini the 1960s many businesses got new
exchanges when they cutover to Centrex and these were all ANC from the
start (eg 448). (One exception was City Hall was which MUnicipal 6.
They've since added 585 to that.)
A tidbit regarding Media, PA: it is served by a trolley line that
connects the town with the 69th Street transit terminal (SEPTA's Rt
101). The trolley runs down the middle of State Street in Media, then
uses private right of way. Media is also served by a commuter rail
station of the ex-Pennsylvania Railroad West Chester branch (now
terminates at Elwyn).
The crossbar in Media was also used for a trial test of push-button
dialing. Modified 300 sets with buttons plucking reeds were used.
I believe Philadelphia was the first installation of the No. 4
crossbar, a toll switch, circa 1944. That and the 4A became a
mainstay of the postwar long distance network.
Bell System history seems to greatly emphasize the No. 5 Crossbar
switch as a major invention capable of so many functions, yet, they
seem to minimize the contributions of the No. 1 crossbar.
