Features of Mobile phone

There are significant questions as to who first invented the camera phone, as numerous other people acknowledged patents filed in the early 1990s for the device, including David M. Britz of AT&T Research in March of 1994 and Philippe Kahn, who claims to have first invented it in 1997. The camera phone now holds 85% of the mobile phone marketplace. Mobile phones often have features beyond transfer text messages and making voice calls, including Internet browsing, music (MP3) playback, memo recording, personal organizer functions, e-mail, instant messaging, built-in cameras and camcorders, ringtones, games, radio, Push-to-Talk (PTT), infrared and Bluetooth connectivity, call registers, ability to watch streaming video or download video for later viewing, video calling and serve as a wireless modem for a PC, and soon will also provide as a console of sorts to online games and other high quality games (e.g. Final Fantasy Agito).
