Hey all,
Does Firefox OS provide any way to uniquely identify a device?
Is this possible both at the UNIX level ('adb shell') and from within
app code (with suitable permission)?
The Android community has been tackling this need for a long time and
has developed multiple approaches though, in modern versions, the OS
provides a way for user code (Java) to obtain a unique id per device. See

* http://stackoverflow.com/questions/13744565/android-device-id-confusion
for discussion of the issues and various solutions.
So far I am poking around in /proc and /sys land from 'adb shell' but
have not yet found anything canonical. There is
cat /sys/devices/virtual/android_usb/android0/iSerial (MSM7627A)
cat /sys/devices/virtual/android_usb/android0/idProduct (9025)
cat /sys/devices/virtual/android_usb/android0/idVendor (05c6)
but I am not sure how 'unique' the iSerial number is. (Note that the
idVendor is probably, in general, related to the list on the page:
http://developer.android.com/tools/device.html
or on the more complete page:
http://www.linux-usb.org/usb.ids
though I am working only from my own device.
I have not yet found a way to extract the IMEI (GSM telephony), let
alone found a way to identify future CDMA devices (ESN/MEID) or devices
without any telephony.
Thanks for any help,
~adrian
