Abstract: Presented herein are techniques to enable a user of an electronic device to re-arrange icons displayed on a display of the electronic device. In one embodiment, a method includes detecting a first movement of the electronic device, detecting a second movement of the electronic device, and in response to the first movement and the second movement, re-arranging groups of icons displayed on the display of the electronic device.

Abstract: A wireless communication device, a power saving method thereof, and a packet filtering method therefor are disclosed. The wireless communication device includes a modem connected to a wireless network system for receiving and transmitting packet data, and a data processor for executing an application program to access network services via the wireless network system. When the data processor is entering to hibernate mode, network information corresponding to the application program is generated, such as a communication port number or an Internet Protocol (IP) address. The modem then filters the received packet data based on the network information. Only when communication port number or IP address contained in the received packet data matches the network information, the modem will wake up the data process to process the received packet data. Therefore, the hibernation time of the data processor is extended to effectively reduce the power consumed by the wireless communication device.
