Miscellaneous features

Other features that may be found on mobile phones include GPS navigation, music (MP3) and video (MP4) playback, RDS radio receiver, vibration and other "silent" ring options, alarms, memo recording, personal digital assistant functions, ability to watch streaming video, video download, video calling, built-in cameras (1.0+ Mpx) and camcorders (video recording), with autofocus[dubious Ц discuss] and flash, ringtones, games, PTT, memory card reader (SD), USB (2.0), dual line support, infrared, Bluetooth (2.0) and WiFi connectivity, instant messaging, Internet e-mail and browsing and serving as a wireless modem. The first smartphone was the Nokia 9000 Communicator in 1996 which added PDA functionality to the basic mobile phone at the time. As miniaturization and increased processing power of microchips has enabled ever more features to be added to phones, the concept of the smartphone has evolved, and what was a high-end smartphone five years ago, is a standard phone today. Several phone series have been introduced to address a given market segment, such as the RIM BlackBerry focusing on enterprise/corporate customer email needs; the SonyEricsson Walkman series of musicphones and Cybershot series of cameraphones; the Nokia Nseries of multimedia phones, the Palm Pre the HTC Dream and the Apple iPhone. Nokia and the University of Cambridge demonstrated a bendable cell phone called the Morph.[11] Some phones have an electromechanical transducer on the back which changes the electrical voice signal into mechanical vibrations. The vibrations flow through the cheek bones or forehead allowing

he user to hear the conversation. This is useful in the noisy situations or if the user is hard of hearing. A GPS navigation device is any device that receives Global Positioning System (GPS) signals for the purpose of determining the device's current location on Earth. GPS devices provide latitude and longitude information, and some may also calculate altitude, although this is not considered sufficiently accurate or continuously available enough (due to the possibility of signal blockage and other factors) to rely on exclusively to pilot aircraft. GPS devices are used in military, aviation, marine and consumer product applications. GPS devices may also have additional capabilities such as: maps, including streets maps, displayed in human readable format via text or in a graphical format turn-by-turn navigation directions to a human in charge of a vehicle or vessel via text or speech directions fed directly to an autonomous vehicle such as a robotic probe traffic congestion maps (depicting either historical or real time data) and suggested alternative directions information on nearby amenities such as restaurants, fueling stations, tourist attractions, etc. In other words, all GPS devices can answer the question "Where am I?", and may also be able to answer: which roads or paths are available to me now? which roads or paths should I take in order to get to my desired destination? if some roads are usually busy at this time or are busy right now, what would be a better route to take? where can I find food, fuel or other needs nearby? the shortest route between two locations
