This IDC study presents our updated forecast for mobile phone shipments, including converged mobile devices and camera phones. Presenting updated splits by air interface, replacement rate, platform, technology, and region, this study provides actual 2004 data and the impact of this demand on IDC's forecast for mobile phone shipments through 2009.

"IDC expects that with strong replacement rates in mature markets and the growing popularity of mobile phones in developing regions, the worldwide mobile phone market will exhibit continued growth in the years ahead. This will allow ample opportunity for handset manufacturers, program developers, and carriers alike. Whereas previous years saw expansion from the introduction of color screens and camera phones, catalysts in coming years will be limited to niche-specific areas that focus on gaming, multimedia, and the enterprise." - Ramon T. Llamas, research analyst, Mobile Devices
