Total Control over the phone

[Marco Miani]

hi everybody
after lurking from the beginning of this list I have a question :
Will we have total control over the GSM module?
I recently bought a Motorola Motofone F3 and my carrier ( Vodafone Italy 
) called me for a firmware upgrade because the cellphone sends 
periodically an sms to a UK number, even if the phone is power off.
Call me paranoid but I don't like a features like this. If my phone is 
power off, it must be like death .....
I know than the GSM firmware is closed due to an NDA, but phone 
developers can assure us that if the phone is power off nothing is done 
over GSM ??
bye bye
