Discusses operating system concepts as they are applied to mobile operating systems using Symbian OS as a vehicle. This book contains a series of online laboratories based on the software developed for Symbian OS devices. It enables students to perform these labs anywhere, and to use printing and e-mail facilities to construct lab write ups.
