The Sony Ericsson K800, and its variant, the Sony Ericsson K790, are the latest mobile phones of their class from Sony Ericsson. Launched in July 2006 (for the K800i in the UK market; others may vary), the phones are the successor to the Sony Ericsson K750i. Both of the phones feature a 3.2 megapixel digital camera complete with a xenon flash, a protective lens cover, and a new "BestPic" bracketing feature, and are the first to be tagged with the Sony Cyber-shot branding. The new "BestPic" feature takes 9 full quality snapshots of a subject in quick succession, allowing the user to choose the best shots from them. Modifications are available throughout the internet to allow the focus light to be used as a light. On the entertainment front, the phones have a media player supporting MP3, AAC/AAC+/eAAC+ and WMA music files and 3GP/MPEG-4 video files. The phones also feature a RDS FM radio, and a Memory Stick Micro (M2) slot for expandable solid state memory.

The difference between the two phones is that the K790 supports GSM and EDGE, while the K800 supports UMTS and GSM. As a result, the K800 features a QCIF (176X144) resolution front-mounted camera for 3G video conferencing. According to the official Sony Ericsson specifications (to be found on their website), the K800's talk time drops steeply from around 7 hours when using GSM to about 2 hours 30 minutes whilst using UMTS. A successor of the K800i, Sony Ericsson K810 will be made available Q2 2007.

The K800/K790 is a "block" (or "candy bar") style phone that weighs 115 grams, with its buttons operated by the thumb. It has the "dual-front" design common to most Sony Ericsson mobile phones since the T610, with the back of the mobile phone designed like a digital camera and intended to be held sideways to take photographs. The central joystick button is used for selecting options and navigating menus, with the "C" button as an undo or delete key, and the arrow-labelled button as a "back button". The two buttons labelled by white horizontal lines, known as hotkeys or soft keys perform the function of making binary decisions, labelled on the phone's display. The button in between the right soft key and the "C" button acts as a shortcut key, which brings up a user-customisable shortcut menu when pressed. The two "A/B" buttons on either side of the earpiece are used for horizontal games support, as in the Sony Ericsson W550/W600. The on/off button is located on the top of the phone. The Memory Stick Micro M2 slot is located on the left-hand side of the phone. On the right-hand side of the phone there are three keys: two for controlling volume, skipping through tracks in the Media Player, changing radio channel, and zooming in and out when in camera mode. The third button on the right is the camera shutter button which operates the phone's key feature, a 3.2 megapixel Cyber-shot digital camera. Located next to this is the IrDA port.

The phone has a standard minimum user-available internal memory capacity of 64 MB. The external memory capacity can be extended by 2 Gigabytes by using a Memory Stick Micro M2, intended to support both the camera and the media player function of the phone. The maximum phone memory is limited by the capacity of the Memory Stick Micro M2. The phone can be connected to a computer for data transfer by using either the built-in Bluetooth wireless or the supplied USB data cable, which connects to the phone using Sony Ericsson's proprietary FastPort connector, which is located on the bottom of the phone. The phone can also be used as a Bluetooth or USB GPRS/3G modem.

K800/K790 cellphones feature full support for USB mass storage recognition. This means that there will be no need for driver installation on modern operating systems such as Mac OS X, Windows XP and Linux, as the phone will be automatically recognized as an external storage device upon connection. Data retrieval also includes the ability to output files by infra-red and Bluetooth (as well as in network-transmitted messages) to other devices. Although typical of many recent Sony Ericsson devices, support for outputting files other than over the mobile network has been variable with other brands.

In the calendar, a new feature is support for recurring event notifications on a yearly basis, which the predecessor K750 lacked. The calendar is closely compatible with Microsoft Outlook.

Apple OS X 10.4.9 added support for calendar and contact syncing under iSync 2.4.

[edit] Camera

The digital camera is capable of taking photographs at four resolutions: 3.2 megapixels (2048x1536), 2 MP (1632x1224), 1 MP (1280x960), and VGA (640x480), with Standard and Fine quality settings at each resolution. It features:

It also has a self-timer, which is useful for self-portraits. A light press of the shutter button initiates the auto-focus feature of the camera lens - when a green dot appears on the screen, the camera has focused, and a stronger press will capture the photograph. The camera also has the ability to capture video clips at 176x144 (QCIF) resolution at 15 frames per second (fps). The camera, which also features 16x digital zoom, is situated on the back side of the phone and is protected by a sliding gloss plastic, metal-effect look cover.

Additionally, the K800 features a small front camera for video telephony using UMTS.
