SIM access profile means 770 can use a cellphone's SIM card (over bluetooth) to authenticate to wifi networks. Such networks are quite rare at the moment, however.

So no, SIM access will not get you to the addressbook of the phone. Most addressbooks are not on SIM anyway. You need to *help* opensync and gpe-pim projects to make that possible
