nokia 7510 T-mobile (unlocked) stop automatic phonebook synchronisation
I did buy this nokia in Europe from the USA, unlocked it here and now everytime I switch on the nokia 7510, it wants to synchronize my phonebook contacts (with T-mobile usa). Of course this service does not work in any way in my country (netherlands), so I tried to make a personal configuration and made this as the default one, so disabled the T-mobile option (I can not delete the T-mobile configuration).
NOw this automatic synchronisation (by GPRS) is stopped, but I can not enter my phonebook /people anymore, i get the message, "ask your provider for the data to set up the connection (something like this). But I do not want to automatically synchronize by gprs every time I swich on the phone (It drains battery etc, messages pop up can not use data packet etc).
