The Sony Ericsson W850i is the first 3Gslider mobile phone by Sony Ericsson, introduced in Q2 2006. It is a member of their Walkman line, succeeding the Sony Ericsson W600. The phone made its first public appearance in the 2006 movie The Da Vinci Code, months before its release. It is similar mechanically to the Sony Ericsson K800i{{cn}}, but differs in form factor, use of the Memory Stick PRO Duo instead of the Memory Stick Micro, and camera quality. (2.0 megapixels instead of 3.2 for the K800i, and with some additional features removed)
The model's features are identical to those of the W880i, apart from the form factor and the inclusion of an FM radio and Photolight on this model.[1] There is also a non-3G version of the W850i called the W830c.
The phone is configured for operator over-the-air (OTA) music download services, and accepts popular music file formats including MP3 and e-AAC+. The box includes a 1 GB Memory Stick PRO Duo.{{cn}} The Golden White version has a gold Walkman logo on the back which the black version does not include.
The Walkman player contains Gracenote Mobile TrackID, which enables a user to record a few seconds of a song, either via the microphone or the built-in FM radio, and attempts to identify the track.
