This IDC Forecast Update is an update to Worldwide Mobile Phone 2007–2011 Forecast and Analysis (IDC #206583, May 2007) and includes data up to and including the first quarter of 2007. Mobile phone shipment numbers include converged mobile device shipment numbers. Prepared before the launch of the iPhone, and owing to lack of clarity on Apple's iPhone-related plans, this update does not account for iPhone shipments.
