This article discusses some issues that a typical Windows C++ programmer will encounter when Approaching Symbian OS for the first time. Our experience in developing for three successive versions of Symbian OS has given us considerable perspective on what can be difficult when working in this otherwise rich and stable environment.

Second-generation telecommunication systems, such as the Global System for Mobile Communications (GSM), enabled voice traffic to go wireless: the number of mobile phones exceeds the number of landline phones and the mobile phone penetration is Approaching 100% in several markets.
