Abstract: This disclosure describes data conversion and techniques for sending and receiving data at a mobile device. In one implementation, a proxy server may receive data from a mobile device. The proxy server may convert the data and send the converted data to a network service. In another implementation, a mobile device may convert data and send that data to a network service. The network service may generate data in response and send that data to the mobile device directly.

Abstract: This disclosure provides techniques for dynamic content caching and retrieval. For example, a computing device includes cache memory dedicated to temporarily caching data of one or more applications of the computing device. The computing device also includes storage memory to store data in response to requests by the applications. The storage memory may also temporarily cache data. Further, the computing device includes system software to represent to the applications of the computing device that the portions of the storage memory utilized to cache content are available to store data of the applications. In addition, the computing device includes application programming interfaces to provide content to a requesting application from a cache of the computing device and/or from a remote content source.

Abstract: Technology for enabling subscribers to reduce their messaging costs is described. The technology includes employing multiple messaging data messaging services and employing advertisement-based defrayal of messaging charges. A message may be entered or displayed as an SMS message even though a data communications service other than SMS is used to exchange the message between computing devices. When a sender of a message sends an SMS message, the sender may receive an advertisement from an advertiser who defrays the cost of sending the SMS message. The advertiser may also defray the receiving cost for a receiver of the SMS message.
