It feels like we haven't heard anything out of Sony Ericsson for a while, which is why we were so excited to learn about the upcoming W715. Essentially a spruced up version of the W705--best known, most likely, for its built-in Walkman--the Sony Ericsson W715 (currently offered in the UK through Vodafone) includes one significant improvement: A-GPS.
No, that's not "a GPS"; it's "A-GPS" as in "Assisted Global Positioning System". It's a satellite location finding feature added to your average, everyday GPS that enhances its capabilities in several ways--not least of which is providing consistent, reliable GPS service even in areas with poor signal quality (such as beneath tall skyscrapers and trees or indoors).
Another frequent problem with standard GPS's that A-GPS addresses is the inability to download almanac and ephemeris info in such conditions until and unless a steady connection can be held for at least 40 seconds (sometimes difficult when, for example, you're on the road and moving).
For effectively using the A-GPS system built-into the W715, Vodafone has included its Find & Go sat-nav software.
