Why would you want to abuse OpenMoko IMEIs in an illegal way, instead of 
arbitrary other larger manufacturer, for a series of phones not built and not 
in use anymore?

You're not owning those IMEIs (they need to be purchased/rented), for OM it 
would be illegal and punishable to support or invite you to use them in the 
way you plan to. And you're exposing OpenMoko device owners to public scrutiny 
by hijacking and abusing this particular IMEI range, possibly resulting in the 
whole IMEI range getting blacklisted on carriers.

@community: It's generally considered a poor idea to disclose your devices' 
IMEIs and particularly in this case you should think twice before you do.
I strongly suggest to use Nokia's 2110 IMEI range instead, or some other 
similar zombie IMEI range for Motorola or whatever.
For Falconia there's not a single benefit from using OM IMEI for that illegal 
purpose.

Thank you for the info!  Thanks to this tidbit from you, we know now
that FIC was quite lax in (not) following the official IMEI rules,
using the same TAC (the first 8 digits of the IMEI) for devices with
different frequency band hardware configs, which is a no-no per the
official rules...

I am still waiting for confirmation on that one, but it also appears
that they used the same TAC for both GTA01 and GTA02, contrary to the
official rule that the TAC must be different for every new model no
matter how minor the change is.  (The *only* difference they allow to
exist within one TAC is the case color!)  The entry for TAC 35465101
in GSMA's IMEI database lists the manufacturer as "FIC" (not Openmoko)
and the model as "FIC Neo1973 Smartphone", so all evidence suggests
that it was originally obtained for GTA01 and later reused for GTA02.
The same IMEI database entry also lists the frequency bands as
"GSM 1800,GSM 1900,GSM 900", so clearly the reuse of the same TAC for
the "US" GTA02 version was a later hack.

My own opinion: while I do not particularly agree with reusing the
same device type code (TAC) for devices with different frequency bands
in the hardware, I fully applaud FIC (or was it OM after they split
off?) for breaking the absolutely idiotic rule about getting a new TAC
for every change in the hardware model, no matter how invisible and
irrelevant a change like GTA01->GTA02 is from the perspective of GSM
networks.  Seeing FIC (or OM) take the TAC that was officially
assigned for GTA01 devices only and reuse it for the GTA02 will
certainly help me justify further reusing the same TAC for my GTA02-
derived FCDEV3B modems. :-)

I live in USA-occupied Incalia (one of the ancient names for the
continent now called North America), specifically on land which USA
wrongfully and forcibly took from Mexico (California), and I use
nothing but GSM/2G cellular devices.  Furthermore, none of these
GSM/2G devices that I use even have that "US" 850 MHz band, instead
they are all "European triband" or what I call tri900 in FreeCalypso,
i.e., 900/1800/1900 MHz, and they make use of the GSM/2G services in
the 1900 MHz PCS band.  The operator is T-Mobile USA.

The FCDEV3B modem board I have built is a clone of the tri900 ("EU")
version of the GTA02 in RF hardware terms.  I would not know how to
build a tri850 version unless someone tells me what SAW filter part
number I should populate for the 850 MHz band in the place of the
B7820 for the 900 MHz band.  I am hoping to never need to build
Om-style tri850 hardware and to go directly to quadband instead
(following TI's Leonardo+ and E-Sample designs) for my next hardware
iteration.

The US GTA02 I still have (FCC EUNGTA02) uses 3546510116x.

I have not tried inserting a SIM, but I have heard that frequencies
have been repurposed and that it probably wouldn't work in the US and
more.

Openmoko IMEI survey

[Mychaela Falconia]

Hello Openmoko and FreeCalypso communities,

I am doing a survey of Openmoko device users to see what portions of
Openmoko's IMEI number range (TAC 35465101, a range of 1 million
possible numbers) have been used to number the 15 thousand or so
devices that have been made, and what portions are unused.  Given that
fewer than 20 thousand units have been made out of the range of
1 million IMEI numbers, simple logic says that at least 98 numbers
out of Openmoko's IMEI range must be still unused, and thus potentially
usable for new production of GTA02 verbatim clones and/or FCDEV3B
boards which are just the modem part of the GTA02.  But I need to make
my very best effort to determine WHICH portions of Om's IMEI range
have already been used, so I use a different subrange for new device
numbering.

Unfortunately it appears that no official factory records of IMEI
assignments have survived the demise of Openmoko-Inc (I tried asking
Sean M-P several times by email, but never heard anything back), hence
I am making my best effort to reconstruct this lost knowledge by way
of a community survey.

To everyone reading this solicitation who owns an Openmoko device: I
would love to hear from you if your device falls into one of the
following 3 cases:

1: If you have a GTA01 (I have never seen one with my own eyes) as
   opposed to the more common GTA02, I would love to hear if the first
   8 digits of its IMEI are 35465101 (same as GTA02) or something
   different.

2: If you have a GTA02 hardware variant with "US" bands, i.e.,
   850/1800/1900 MHz (FCC ID EUNGTA02), as opposed to the much more
   common "EU" variant (900/1800/1900 MHz, FCC ID EUNGTA02E), same
   request as above: I would like to know if the first 8 digits of the
   IMEI are 35465101 or something different.  Like with the GTA01, I
   have never seen a "US" FreeRunner with my own eyes.

3: All Openmoko devices, whether GTA01 or GTA02, "EU" or "US": if the
   first 8 digits of your IMEI are 35465101, but the following two
   digits are something other than 16 or 96, I would like to know what
   those two digits are.

The two digits after the 35465101 TAC prefix are the first 2 digits of
the 6-digit SNR (serial number) field, and it is the usage of this SNR
space that I am after.  So far the only Openmoko devices I have laid
my hands on have been GTA02 "EU" version units, their TAC has always
been 35465101, and the SNR field has always been either 16 on
older units or 96 on newer ones.  However, if there have been
Openmoko devices made with something other than 16 or 96 in
the SNR field of the IMEI, I would really like to know about them so I
can avoid stepping on those subranges and pick a subrange that has not
been used at all.

TIA for your participation in the survey,
