1. A mobile electronic device, comprising:
- a processor;
a user input device connected to the processor for sending signals to the processor;
a display screen connected to the processor;
a communication sub-system connected to the processor for exchanging signals with a wireless network and with the processor;
a plurality of application modules associated with the processor for implementing applications on the mobile electronic device;
a storage element connected to the processor and having data stored thereon, the data comprising at least service data required to establish communications with the wireless network and user application data associated with the application modules; and
a security module associated with the processor for displaying on the display screen a plurality of selectable items upon detecting a predetermined security input through the user input device, displaying on the display screen a window comprising a prompt for further input in response to an input selecting a predetermined one of the selectable items, and performing a security action comprising deleting or encrypting all service data and/or all user application data stored on the storage element while maintaining other data stored on the storage element subsequent to a further input in response to the prompt,wherein the security module is configured for entry of a predetermined word and to perform the security action only if the predetermined word is correctly entered subsequent to displaying the prompt for a further input, andwherein the security module is configured to display as part of the prompt the predetermined word prior to entry of the predetermined word.

Abstract
A mobile communications device for communicating with a wireless network. The device includes a processor, a communications sub-system connected to the processor for exchanging signals with the wireless network and with the processor, a user input device connected to the processor for sending user input signals to the processor in response to user inputs. A security module is associated with the processor for automatically taking a security action upon detecting a predetermined security user input through the user input device. The security action can include sending a duress message and/or wiping data stored on the device.

10. A method of providing security for data stored on a wireless communications device, the wireless communications device comprising a processor and a storage element connected to the processor and having data stored thereon, the data comprising at least service data required to establish communications with a wireless network and user application data associated with the application modules or implementing applications on the wireless communications device, the method comprising the steps of:
-
displaying a list of selectable items on a display screen of the wireless communications device upon detecting a predetermined security input through an user input device; providing the wireless communications device with an input device enabling movement of a selection indicator among the items of the displayed list; in response to a selection of a predetermined one of the selectable items, displaying on the display screen a window comprising a prompt for a further input; and subsequent to a further input in response to the prompt, performing a security action comprising deleting or encrypting all service data and/or all user application data stored on the storage element while maintaining other data stored on the storage element, subsequent to receiving the further input, displaying on the display screen a further window comprising a prompt for yet a further input, wherein the security action is performed only if the yet further input is received through the input device subsequent to receiving the prompt for yet a further input, and wherein the further window comprises a word and instructions to enter the word as the yet further input to proceed with the security action. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
