The Sony Ericsson T610, released in 2003, is a mobile phone manufactured by Sony Ericsson. It was one of the first widely available mobile phones to include a built-in digital camera, Bluetooth, color screen, joystick navigation, and was a very high selling model. The T630 was a later variant. The T610 is available in three distinct colors: Aluminium Haze, Abyss Blue, and Volcanic Red. Many customers of Sony Ericsson in the United Kingdom complained to providers about being unable to obtain the phone in any color other than Aluminium Haze, and to date it is still the most widely sold variant of the phone. The retro-style design of the phone was created by industrial designer Erik Ahlgren, and garnered appreciation in magazines, at expositions, and among buyers. The subtle curves of the body were divided vertically with thin metal or aluminum halves, which were colored. The keypad remained silver regardless of body color variation. The T610 is a cameraphone that can take pictures in a resolution up to 288 × 352 pixels. It includes 2.5G technologies, supporting GPRS (Class 8) and HSCSD connections with Wireless Application Protocol (WAP) 2.0 capability. It supports polyphonic ringtones in MIDI, and mobile games in Java ME and Mophun formats, and comes with three games. It does not have built-in handsfree or speakerphone capabilities, however. The latest firmware version for the T610 is R7A011.
