Abstract: Improved mobile content presentation capabilities are disclosed for mobile communications facilities, such as cell phones. Information relating to the user characteristics associated with a mobile communication facility and other capabilities are employed to improve the presentation and relevance of mobile content to appropriate or desirable mobile communication facilities.

Abstract: A system for identifying a same user of multiple communication devices is configured to perform the steps of: (a) receiving first data relating to a first device operated by a user; (b) receiving second data relating to a second device operated by a user; (c) determining that the user of the first device is the user of the second device based on identifying that the first data is substantially the same as the second data; and (d) selecting and transmitting a sponsored content to the second device for display thereon, wherein the sponsored content has a relevance to the first and second data and/or a user characteristic datum associated with the user.

Abstract: A system for receiving data associated with a mobile content is configured to calculate an expected value of the mobile content based at least in part on the data received, and determine a bid amount for a sponsorship of the mobile content based at least in part on the expected value.

Abstract: In embodiments of the present invention improved capabilities are described for caching search related data on a mobile communication facility, coordinating the presentation of the cached information with network information to the mobile communication facility display to facilitate response to user queries with up to date information, and implicitly downloading updates to cached information while previously cached information is available to the user.
