Make your smart phone smarter

During the past few years, the mobile phone has become so much more than a telephone. As PDAs such as the Palm Treo have merged with telephones, cell phones themselves have started acting like PDAs. Aside from the obvious address book and calendar, a common phone on the street might have a digital camera, an MP3 player, an instant messenger, and a GPS locating device.One of the most popular mobile-phone operating systems is Symbian, powering Nokia and Sony Ericsson models, among many others.
