Microsoft is launching a service that allows Windows Mobile users to synchronise and store data from their mobile device to the web.
The free My Phone service will provide space to store photos, videos, text messages and calendar items.
Users will be able to share the data with others as well as using the service as a back-up service.
More details about My Phone are expected to be revealed at next week's Mobile World Congress show in Barcelona. My Phone will initially be released as a beta.
My Phone is currently limited to users running mobile devices equipped with Windows Mobile 6, but it is expected to be compatible with the forthcoming Windows Mobile 6.5.
