Abstract: A method is provided for navigation in a tab-based application interface on a touch-sensitive display of a portable electronic device. A start of a touch contact initiating proximate to a first edge of the touch-sensitive display is detected. An end of the touch contact terminating proximate to a second edge of the touch sensitive display is detected. An angular gesture can then be determined when the start of the touch contact and the end of the touch contact are from the first edge being perpendicular to the second edge of the touch-sensitive display. Content associated with a tab on the touch-sensitive display in the tab-based application interface in response to the angular gesture is then displayed.

Abstract: Disclosed is a system, method, and computer program product for exchanging categorized information nuggets stored in a database accessible to a portable mobile communication device with other similarly equipped portable mobile communication devices. The presence of another portable mobile communication device capable of exchanging categorized information nuggets is discovered and a connection is established. Information nugget category data is exchanged with the other portable mobile communication device to determine whether there are common categories shared by each portable mobile communication device. Information nuggets for common categories are then exchanged with the other portable mobile communication device. The information nuggets can be displayed and saved by the receiving portable mobile communication device. The information nuggets can also be date/time and location stamped to add additional contextual data about the information nuggets.
