Abstract: A mobile wireless device that transmits messages to recipient devices that correspond to subscribers of a service for receiving packet-switched messages may poll a community of users of the service. Each user of the community of users may receive, in response to the poll, an indication to select a voting button. The mobile wireless device may receive poll responses from the community of users of the service. The poll responses may comprise predetermined text in order to minimize the potential of false responses that cannot be counted.

Abstract: A mobile wireless device may transmit message content intended for a third party provider, to a server associated with the service, which forwards a message comprising the message content intended for the third party provider, to the third party provider. The message forwarded to the third party provider may be derived at least in part from a random number. The message forwarded to the third party provider may not be identical to a message transmitted by the mobile wireless device comprising the message content intended for the third party provider. The message transmitted by the mobile wireless device comprising the message content intended for the third party provider may include at least one information element which is not included in the message forwarded to the third party provider.

Abstract: A method may comprise receiving, from a first handset via the Internet, a subscription message for subscribing the first handset to a service for receiving packet-switched messages other than SMS messages, EMS messages and MMS messages. The method may further comprise storing information indicating that a first mobile phone number of the first handset corresponds to a subscriber of the service, in a subscriber data store. A first request may be received, from a second handset, the first request including at least information corresponding to the first mobile phone number of the first handset. The first mobile phone number of the first handset may be determined to correspond to a subscriber of the service. A first response may be transmitted to the second handset.

Abstract: A mobile wireless device may transmit at least some messages to at least some recipient devices that correspond to subscribers of a service for receiving packet-switched messages, wherein the service includes a server that receives packet-switched messages transmitted via the service to recipient devices that correspond to subscribers of the service and at least some messages over a cellular network to at least some recipient devices that do not correspond to subscribers of the service. The cellular network may include a core network.

Abstract: A wireless device for providing a message service is disclosed, along with a computer readable medium. The wireless device may be capable of sending messages via a packet switched WLAN base station in a first mode, or via an SMS base station that is independent of the packet switched base station, in a second mode. A message client on the wireless device determines whether a recipient's wireless device corresponds to a subscriber of a service for receiving the outgoing message via a packet switched bearer. The wireless device sends, via a WLAN transceiver, if the recipient's wireless device corresponds to a subscriber of the service, the outgoing message to the recipient's wireless device in the first mode. Alternatively, if the recipient's wireless device does not correspond to a subscriber of the service, the outgoing message is sent by a cellular transmitter via the SMS base station in the second mode.
