w850

The Sony Ericsson W850i is the first 3G sliding form factor mobile phone for Sony Ericsson, introduced in Q2 2006. It is a member of their Walkman line. 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, but differs in its form factor, memory card support of the Memory Stick PRO Duo instead of Memory Stick Micro, and the camera (2.0 megapixels instead of 3.2 for the K800i, and with some additional features removed)
The phone is available in Precious Black or Golden White and is configured for operator over the air (OTA) music download services and accepts popular music file formats including e-AAC+, and includes a 1 GB Memory Stick PRO Duo. 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 in-built FM radio, and then with one click send that clip to the Gracenote worldwide music database which will identify the track and relay the information back to the phone.
The model shares all the features the W880i has except the form factor and the inclusion of an FM radio and Photolight on this model.There is a non-3G version of the W850i called W830c.
