IccPhoneBookInterfaceManager will decide which Card App to use.

Phone will not tell IccPhoneBoookIntefaceManager which record
to use. Phone will only provide the card associated with it.

PhoneBook will iterate through the apps on the card to
determine if it is a 3G or 2G card and use EF_PBR or
EF_ADN respectively.

Reset mIs3gCard flag before determining if present card is 3G.
