Wireless modem(s) 1460 can be coupled to antenna(s) (not shown) and can support two-way communications between processor 1410 and external devices, as is well understood in the art. Modem(s) 1460 are shown generically and can include a cellular modem 1466 for communicating with the mobile communication network 1404 and/or other radio-based modems (e.g., Bluetooth 1464 and/or Wi-Fi 1462). At least one of wireless modem(s) 1460 is typically configured for communication with one or more cellular networks, such as a GSM network for data and voice communications within a single cellular network, between cellular networks, or between the mobile device and a public switched telephone network (PSTN).
Mobile device 1402 can further include at least one input/output port 1480, a power supply 1482, a satellite navigation system receiver 1484, such as a Global Positioning System (GPS) receiver, an accelerometer 1486, and/or a physical connector 1490, which can be a USB port, IEEE 1394 (FireWire) port, and/or RS-232 port. The illustrated components of mobile device 1402 are not required or all-inclusive, as any components can be deleted and other components can be added as would be recognized by one skilled in the art.
In an embodiment, mobile device 1402 is configured to implement any of the above-described features of flowcharts herein. Computer program logic for performing any of the operations, steps, and/or functions described herein may be stored in memory 1420 and executed by processor 1410.
