Abstract: A method and system for implementing a security technique enables an electronic device to run controlled test applications. An enabler application sets up specific devices as testing devices by encrypting the serial number of the device and an assigned authorization level and storing these encrypted values on the device. A test application that has controlled attributes is allowed to run on any device that has been correctly enabled with an authorization level that is of an equal or higher value than the authorization level assigned to the test application.

Abstract: A handheld computer system is disclosed. The handheld computer system includes a housing, a display supported by the housing, and a processor coupled to the display. The handheld computer system also includes a rechargeable battery configured to power the processor and the display. Further, the handheld computer system includes a recharging connector coupled to the rechargeable battery. Further still, the handheld computer system includes a recharger coupled to the recharging connector. Yet further still, the handheld computer system includes a radio frequency transceiver coupled to the processor and powerable by the battery when the battery has a charge above a predetermined low level, the transceiver configured to send and receive data while the battery charge is below the low level and the charger provides charge to the rechargeable battery and to the transceiver.

Abstract: A user sets up an account including radio identification, billing information, etc. via a web-based account creation device, or over the telephone with an account representative. An activation key is provided to the user that identifies the radio device and the users account. An activation screen is displayed to a user at the start of wireless activities. The activation screen requires the activation key before continuing with wireless services. Since the key identifies both the radio and user's account (which was approved prior to provision of the activation key), rejection traffic is eliminated and non-active account traffic is significantly reduced.

Abstract: A panel has been provided to a wireless device that turns off all RF capability of the wireless device (including, but not limited to notifications, wireless web clipping, instant messaging, email sending/receiving, phone calls, etc.). The panel is brought up on a screen of the wireless device by pressing a programmed hard button for more than 1 second. Once the RF capability has been turned off, if the user attempts to access a program or other device that requires the RF capabilities, a notification is displayed that identifies the RF capabilities as being disabled and prompts the user whether to continue. If the user continues, the RF device is automatically enabled, otherwise the RF device remains disabled.

Abstract: A method and system for establishing a wireless connection between a portable computer system and a wireless network, particularly when the portable computer system goes out of coverage and a wireless connection needs to be re-established. The portable computer system has a main processor and a digital signal processor (DSP). The main processor is placed in a low power mode, conserving battery power. When the portable computer system goes out of coverage, broadcast channels used by the wireless network are scanned by the DSP instead of the main processor to identify channels that have sufficient signal strength for the wireless connection. Thus, the main processor remains in the low power mode. When the DSP identifies acceptable channels, it wakes up the main processor and identifies the channels having sufficient signal strength. The main processor then establishes a wireless connection using one of the channels identified by the DSP.

Abstract: A wireless e-mail messaging system is disclosed. The wireless e-mail messaging system includes a communications network. The wireless e-mail messaging system also includes a portable electronic device including a transceiver configured to establish a wireless link to the communications network. The portable electronic device includes a wake mode in which the wireless link is established and messages may be sent and received by the portable electronic device and a sleep mode in which the wireless link is not established and messages may not be sent and received by the portable electronic device. The portable electronic device includes a program to randomly select a time to transition from the sleep mode to the wake mode during a predetermined time interval.
