Linda has been a known codename for quite some time now, but until now we really haven't had any phones to match with the codename. Today, a bunch of photos of the upcoming W595 - W580 successor - leaked on Journaldugeek.
The W595 is very much like the W580 when it comes to its design. It is - in my opinion - a bit more slick, but the colours and the overall look is very much like W580's. As far as I know, this will also come in a white & red colour variant.
W595 is a Walkman phone, featuring the Walkman 3 player, as well as an FM radio. It is based on the A2 software platform, and will come bundled with the location services, including Google Maps. W595 will also feature a fully-specced 3-dimensional accelerometer, unlike the 2-dimensional one present in W580.
