The method additionally includes receiving an update to the content from the first user at a second time which is later in time than the first time, determining whether one or more second users should be notified of the received update based on an associated second priority level, and sending a second notification to these second users. The second notification includes a second subset of the user-facing information associated with the received update.

Abstract: In particular embodiments, a messaging device or server may be operable to receive a message including a thread identifier or a list of conversation participants; if the message includes a thread identifier, then append the message to a locally-stored conversation thread possessing the same thread identifier; if the message includes a list of participants, then: search a plurality of locally-stored conversation threads for a conversation threads having participants matching the list of participants; and in response to a match, append the message to the matching thread; in response to failing to find a match, generate an offline identifier for the message and storing the message locally.

Abstract: In particular embodiments, a mailbox server is operable to receive, from a client, a message to be delivered to an endpoint; store the message in a mailbox associated with the user; access a set of policies for the client or the endpoint; determine a delivery channel for the message based on the policies; and transmit the message to the endpoint through the delivery channel. In particular embodiments, the mailbox server may transmit SMS messages via a special bind with a recipient's SMSC, or via a carrier short code. In particular embodiments, the mailbox server may transmit the message as an email or via an internal messaging system over a packet data connection.

Abstract: In one embodiment, a method includes receiving a request at a wireless access point from a client system to access a network through the wireless access point. The wireless access point sends an identifier associated with the client system to a social-networking system, the social-networking system including user profiles arranged in one or more social graphs. The social graphs store relationships between the user profiles. The method further includes receiving at the wireless access point from the social-networking system an authorization determination. The authorization determination is based upon a first user profile of the plurality of user profiles. The first user profile includes the identifier associated with the client system. The method further includes providing the client system with access to the network through the wireless access point in accordance with the authorization determination.

Abstract: Methods and systems directed to retrieving voicemails from a voice mailbox server. In particular embodiments, a mailbox server may receive a notification from the voice mailbox server and connect to the voice mailbox server providing the credentials of a client device, and pull new voicemails for storage at the mailbox server. In particular embodiments, mailbox server periodically polls voice mailbox server for new voicemail messages. In particular embodiments, a client device polls or receives notification of new voicemails, and transmits a downloaded message to the mailbox server.

Abstract: In one embodiment, a method includes receiving a first notification through a communications network. The first notification includes a subset of user-facing information of an object having one or more states, the subset being determined at a first point in time. A second notification is received through the communications network. The second notification is an update to the user-facing information of the object, and the update may be a subset of user-facing information determined at a second point in time after the first point in time.

Abstract: In one embodiment, a mobile device connecting to a Wi-Fi hotspot first performs a connectivity check to determine whether the wireless connection is trapped in the walled garden of a captive portal by transmitting a connectivity check message to one or more external endpoints in the public IP network. If no response is received, the mobile device determines that it is in the captive portal state, and generates a browser window bound to the Wi-Fi state tracker of the mobile device displaying the portal page for the captive portal. In such a manner, the mobile device does not offload any traffic from its wireless cellular interface to its Wi-Fi interface until it is certain the Wi-Fi interface may access the public IP network, thereby preventing data interruption for mobile applications.

Abstract: Methods and systems directed to assigning individual messages and call log data into an aggregated conversation thread on both client and server devices for a user interface having a conversations view including all the communications a given users has with his or her contacts across multiple communication means and protocols. Messages between a user and a particular contact are threaded together, regardless of their format or protocol in order to provide the user with a quick history of all communications with his or her contacts.

Abstract: In one embodiment, a method includes iteratively waiting for a time interval; sending a keep-alive message from a first computing device to a second computing device; and incrementing a current value of the time interval when the first computing device receives from the second computing device a response to a current keep-alive message sent during the current iteration, until the first computing device does not receive from the second computing device any responses to the current keep-alive message sent during the current iteration; and setting the current value of the time interval to a previous value of the time interval from an immediately-previous iteration.

Abstract: A method and system for aggregating capabilities from multiple endpoints associated with a user are provided. The system aggregates the capabilities of the endpoints associated with a user into an aggregate view of available modes of communication for reaching the user. Then, the system publishes the aggregate view so that other users who want to send communications to the user will know the modes of communication available for that user. In addition, the system may designate certain modes of communication as preferred or as capable of reaching the user.
