On April 4, 2006 Sony Ericsson announced the eighth member of the Walkman family of music mobile phones, the W700, which builds on the legacy of the first Walkman phone, the W800. 
 

This tri-band GSM/GPRS phone offers great quality stereo music, 34MB internal storage, extended storage using up to a 2GB Memory Stick PRO Duo, a 2 Megapixel still and video camera, HTML browsing and 3D gaming. Music files can be stored in industry standard MP3 and AAC formats, enabling legacy CD collections to be easily transferred to the phone with the accompanying Disc2Phone PC software. Multimedia file formats supported by the W700 include: Sound: MP3, AAC, MP4, M4A, 3GP, AMR, WAV, G-MIDI Video: MP4, 3GP Pictures and Animation: JPEG, BMP, GIF (including animated), PNG, WBMP, Macromedia Flash, SVG Music-related Java ME application opportunities Moving beyond just music tracks, Sony Ericsson Developer World stimulates other music-related application ideas and has set up a dedicated music web resource at www.SonyEricsson.com/developer/music.

The W700 Walkman offers developers a range of JSRs to create music-related applications and advanced 3D games:

• JSR 75 PDA Optional Packages for the Java ME Platform:
  Implemented in a range of phones to permit Personal Information Management (PIM) data access and file system access, for example accessing music files, images or phone book
• JSR 82 Java APIs for Bluetooth:
  Enables PC connectivity from mobile Java applications, files or data transfers via Bluetooth to and from other devices, and wireless multi-player gaming
• JSR 172 Java ME Web Services Specification:
  Now implemented in the W700 and the other Walkman phones including the W300, W600, W550, W900, W810 and W950, as well as in the P990 smartphone and the M600 messaging device to take advantage of a lightweight XML parser to create powerful MIDlets that are comparable to Java SE counterparts
• JSR 184 Mobile 3D Graphics API for Java ME:
  Implemented in a broad portfolio of 33 Sony Ericsson mobile phones to encourage mobile three-dimensional gaming and other non-gaming related applications such as 3D GPS mapping, avatars, user interfaces adding depth (3D instead of SVG), and 3D virtual walk-throughs of various scenes
• JSR 205 Wireless Messaging API 2.0:
  Enables the sending and receiving of Short Messaging Service (SMS) and Multimedia Messaging Service (MMS) messages from Java ME applications
