What do you exactly want to do ?

What device are you experiencing on ? How did you flashed it ?
As far as I can say, iSerial should not be overwritten in public devices
and build, but it's the case on some build you can do by yourself.

IMEI should be available in mozTelephony API, though this is probably
only available to certified apps. CDMA will be supported in upcoming
releases (1.2 or 1.3, I don't remember exactly), but for sure we have no
device with CDMA yet available. Distinguishing between GSM and CDMA
should also be possible through the same mozTelephony API.
