Apple iCloud to compete with Amazon and Google services
Apple's new iCloud service allows photos, documents and music to be passed from one device to another over the web.
The data is stored in Apple's servers and can also be accessed wirelessly by phones, computers and tablets.
The company's upcoming launch of the service follows those of rivals Amazon and Google who have already launched their own cloud based services.
