The Motorola Slvr (styled SLVR) is a series of mobile phones from Motorola, and is one of the series in the 4LTR line. The first phones were out in early 2005. They are designed to be very thin and lightweight.
The SLVR is featured in the NSA ANT catalog as a variant costing $15,000 and containing a software defined radio for covert surveillance.
The Slvr L2 was introduced in 2005. The L2, which lacks a camera, external memory, and music features, is marketed specifically to corporate and government markets which generally prohibit their employees from using phones with the listed features. It is not marketed specifically under the Slvr designation.
The Slvr L6, also from early 2005, was released shortly before its heavily advertised brother, the L7 (see below). The L6 held the title of the thinnest mobile phone in the UK for a short while, before being beaten by the Samsung P300. Features of the L6 include Bluetooth, MP3 ring tones, camera and video on it. It is basically a cut-down version of the Slvr L7 with all functions except for iTunes ( US only) and the use of external memory. The Slvr L6 also has a smaller screen than that of the Slvr L7.
