Systems, methods, and software can be used for securing in-tunnel messages. One example of a method includes establishing a tunneling connection between a server and an endpoint. The method further includes receiving a packet from the server over the tunneling connection. The method yet further includes determining that the packet comprises a tunneling control message based on at least one address in the packet. Based on the determination of a received packet comprising a tunneling control message, the method can ensure the security of in-tunnel messages based on an indication in the tunneling control message.

Secured in-tunnel messages and access control

Systems, methods, and software can be used for establishing a tunneling connection over restrictive networks. One example of a method includes selecting, at an endpoint, at least one protocol to be used to establish a tunneling connection between the endpoint and a server. The at least one protocol is one of transmission control protocol (TCP) or user datagram protocol (UDP). The method further includes transmitting data between the endpoint and the server over the tunneling connection by using the selected at least one protocol.

Establishing tunneling connection over restrictive networks

A method for controlling an orientation of a display of a wireless device using a combination of accelerometer-determined orientation and camera-determined orientation, the camera being a frontal camera used to confirm or reverse the orientation found by the accelerometer.

Display orientation change for wireless devices

An improved handheld electronic device includes an Application Programming Interface (API) that generates various notifications in certain circumstances. The handheld electronic device provides an improved method of employing the notifications to enable another device to reflect a change to a browser cache on the handheld electronic device.
