The LG KS20 is a high-end card bar style smart phone. The KS20 differentiates itself from similar devices with its small size and light weight as well as its aesthetics. The styling of the case is similar to that of the Prada II phone, made from black high-gloss plastic with metal trim. This gives the handset a design which is on par with many fashion phones on the market, though the KS20 is not marketed as such. Instead, it is sold as a high-speed media and internet phone, focusing on the device's 3.6Mb/s HSDPA capability. While there is no 3.5mm jack for headphones, there is an included adapter in the box. The KS20 comes with Windows Mobile 6, and a customized interface.
