Abstract: A method and system for securing data of a mobile communications device. The method includes: determining that first application data is data associated with a first server; encrypting the first application data with an encryption key stored in the mobile communications device; storing the encrypted first application data on a memory; receiving a request to access the first application data from an application or a service implemented from the mobile communications device; determining that the application or service is authorized to access the first application data; and in response to said determining, decrypting the first application data with the encryption key.

Abstract: A communication device and method are provided for storing and updating file system information for a network resource such as a content server or application server over a wireless connection. Data pertaining to a folder structure or content listing is received at the device and stored in persistent memory. Upon determination that the stored file system information has aged beyond a predetermined threshold and that a last modification time for the network resource is later than a time associated with the first file system information, a request is transmitted over a wireless connection for new file system information for the network resource. The request may be intercepted by a mobile data server that communicates with the network resource to provide the information to the communication device.
