Abstract: An apparatus, system, and method for controlling access to sensitive data in a wireless handset using password protection are disclosed. The wireless handset comprises an input module, a memory module, a display module, and a control module. The input module is configured to manually receive one or more passwords that are input into the wireless handset. The memory module is configured to store at least one password associated with a user-requested function. The user-requested function has a plurality of user-specific data stored on the memory module. The display module displays the stored user-specific data. The control module controls the operation of the input, memory and display modules. The control module controls access to the user-specific data with an initial password received with the input module.

Abstract: An exemplary method for displaying address book entry data on a mobile wireless communication device comprises displaying a list of contacts entries on a display, receiving first input indicative of selection of one of the contact entries, receiving second input indicative of a request for historical transactions associated with the selected one of the contact entries, and displaying a list of historical transaction associated with the selected one of the contact entries in response to the second input. The method may further include retrieving an entire historical transaction log (e.g., phone call history log or message history log) from memory, and filtering the entire historical transaction log to generate a temporary transaction history.

Abstract: An apparatus, system, and method for controlling access to sensitive data in a wireless handset using password protection. The wireless handset comprises an input module, a memory module, a display module, and a control module. The input module is configured to manually receive one or more passwords that are input into the wireless handset and may be associated with a user-requested function. The memory module is configured to store the passwords associated with the user-requested function. The user-requested function comprises a messaging function selected from a messaging group consisting of IM, SMS, MMS, and user contacts data. The user-requested function has a plurality of user-specific data stored on the memory module. The display module displays the stored user-specific data. The control module controls the operation of the input module, the memory module and the display module.
