Abstract: Mobile communication terminals comprising a processor unit, a microphone, and a sound processing module for processing sounds captured by the microphone. The processor unit is configured to operate the terminal for a push-to-talk communication with at least one other mobile communication terminal via the communication network, and to operate the terminal during said push-to-talk communication in a latency state or in an active state in which sound captured by the microphone is processed by the sound processing module and sent to the at least one other mobile communication terminal. The processor unit is also configured to change from the latency state to the active state in dependence of the sound captured by the microphone.

Abstract: Systems and methods for the automatic or streamlined customization or configuration of mobile devices are provided. In accordance with one embodiment of the present invention, a mobile device is provided with an installation agent that aids in installation of new device applications by fully or partially automating the installation process. Another aspect of the invention includes providing a mobile device with an error-handling agent that streamlines or automates the process of correcting device malfunctions. Other aspects of the invention are-concerned with providing simplified user interfaces for mobile devices and enabling the remote control and manipulation of a mobile device.
