Abstract: A mobile telecommunications device configured for use with an online service provider is disclosed that includes a processor and memory in electronic communication with the processor. Instructions are stored in the memory. The instructions are executable to implement a method for setting a presence based on a flip state of the mobile telecommunications device. The mobile telecommunications device connects to the online service provider. The flip state of the mobile telecommunications device is determined. The presence is set based on the flip state. The presence is communicated to the online service provider.

Abstract: An application manager receives a descriptor for a MIDlet update from an MIDP server system. The application manager determines that the descriptor identifies an update to a MIDlet that is already installed on the MID. The application manager also identifies the MIDlet for which the update is intended, and determines that the update is valid with respect to the MIDlet. The application manager provides information from the descriptor to the user of the MID. If the user decides to download the update that corresponds to the descriptor, the application manager sends a request to the MIDP server system to transmit the MIDlet update to the MID. When the application manager receives the MIDlet update from the MIDP server system, an installer installs the file(s) of the MIDlet update in the existing MIDlet.

Abstract: An exemplary method may be performed by a server system that implements the Mobile Information Device Profile. In accordance with the method, one or more files are provided that extend a MIDlet with additional functionality. The files may include Java® class files, content files (e.g., images), etc. A packaging component packages the files to create a MIDlet extension. The packaging component creates a descriptor for the MIDlet extension. The packaging component adds extension properties to the descriptor. The extension properties identify the MIDlet extension as an extension to the MIDlet and facilitate discovery of the MIDlet extension. The descriptor is associated with the MIDlet extension.
