[maemo-developers] Is wireless modem support police functions

[From: DmitryTurin.narod.ru]

*) Is wireless modem specify in packages the factory number of equipment like Ethernet-card?
(this number in Ethernet-packages has cynical name "MAC-address")

*) If so, sending of number is result of work of OC or of wireless modem itself?

*) If last case, factory number is burned just inside sending/seceiving chip,
or is stored outside on flash or ROM of wireless modem?

*) If outside, than where - on flash or on ROM?
In the first case: is flash re-programmable just from phone,
 without putting flash into additional device?
In the second case: is it hard to buy clear ROM and device-programmer for ROM?
