Re: chip of cellular/wireless modem
>Anyway - you can't practically break the signature algorithm of the firmware signing - unless there is some defect in the code. Probably, we do not understand each other. I need to send package with abnormal AKEY, that cellular provider does not withdraw money for call to not him (to not provider). It seems much more easy, than to sign by _normal_ AKEY of other cellular number, which you imply. I do not need to break signature algorithm at all (for second modem in phone). ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

For various technical reasons - there are hundreds of channels, and the modem can be tuned to only one, amongst others. Also, for legal reasons the software which runs on the modem chipset will not support this. This software is completely seperate from the application softwae - maemo/meego. *) send package with abnormal AKEY (or abnormal SIS) than it is necessary to patch code of "pnatd", working directly with modem, or some other code? You would need to break the signature algorithm in the modem code signing, reverse engineer the interfaces, and then binary patch the modem code to add this functionality. Distributing this code - in the UK - for example - would then be a criminal act - once it's first used to do criminal acts, and you've been notified of this. 'manufacturing' this code for the first time would be a seperate offence. In short - find another platform where it can be done. ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers

The 770, N800 and N810 do not contain any cellular device at all. They are not phones, they were sold as "Phone Accessories". To get connectivity they could connect to a phone via Bluetooth, or they could use WiFi.
