Finally, you must consider how you will interact with remote services that provide the data used by your application. You can interact with many types of services, including cloud services such as Windows Live® network of Internet services, and the Location Service and Notifications Services that are specifically designed to integrate with Windows Phone 7 devices. Technically, the format of the data you use to drive your application is irrelevant, though you should consider interoperability with other devices, communication security, and whether you need to perform data or file synchronization between the device and the server. However, it is vitally important to consider the bandwidth utilization, transfer volumes, and the costs of connectivity for your chosen approach.
