Originally created by Bosch, the S40 model is Siemens first tri-band (GSM 900/1800/1900) mobile phone and can be used in every GSM network in the world. After buying Bosch's mobile phone division the phone was released by Siemens with minor changes to the software and design. Additional features includes 10 minutes voice memo, WAP, HSCSD, calendar and capability to sync with Microsoft Outlook. The phone has a metallic front with blue backlight. It is also very durable. Almost every Friday I accidently drop it on asphalt around 3.00 AM and it survives with only some additional scratches ;)
