Methods and apparatus for use in transferring user data between two different mobile communication devices using a removable memory card
First Claim
1. A method for use in transferring user data associated with a user account from a first mobile communication device having a first personal information manager (PIM) application to a second mobile communication device having a second PIM application, the first mobile communication device including a memory, an interface configured to receive a removable memory card, and first and second wireless transceivers, the method comprising:
- maintaining storage of an encryption/decryption key in the memory;
refraining from maintaining encryption/decryption key in the removable memory card;
maintaining data synchronization of the user data, via a wireless communication network using the first wireless transceiver, between the first mobile communication device having the PIM application and a host server;
for the data synchronization;
regularly receiving and storing updates to the user data in the memory for use in the first PIM application;
for updates to the user data, updating a copy of the user data stored in the removable memory card in an encrypted format in accordance with the encryption/decryption key;
causing the encryption/decryption key to be transmitted to the second mobile communication device via the second wireless transceiver;
after the removable memory card is transferred from the first mobile communication device to the second mobile communication device, copying the user data from the removable memory card to memory of the second mobile communication device; and
maintaining data synchronization of the user data, via the wireless communication network, between the second mobile communication device having the second PIM application and the host server.

Abstract
A source device is initially enabled to maintain data synchronization with a host server over a wireless communication network via a first wireless transceiver for user data of an application program associated with a user account. To enable a target device, the source device is operative to establish a programming session with the target device via a second wireless transceiver. During the programming session, the source device causes user account data (e.g. an encryption/decryption key for the data-synchronized communications) for the user account to be transmitted to the target device via the second wireless transceiver. The user data associated with the application program may be transferred from the source device to the target device via a removable memory card such as a secure digital (SD) card.
