Abstract: A portable electronic device for instant messaging is disclosed. One aspect of the invention involves a graphical user interface (GUI) on a portable electronic device with a touch screen display. The GUI has a set of messages exchanged between a user of the device and another person. The set of messages are displayed in a chronological order. In response to detecting a scrolling gesture comprising a substantially vertical movement of a user contact with the touch screen display, the display of messages are scrolled in accordance with a direction of the scrolling gesture. The detecting of the scrolling gesture is substantially independent of a horizontal position of the user contact with the touch screen display.

Abstract: A device with a touch-sensitive display may be unlocked via gestures performed on the touch-sensitive display.

Abstract: A portable multifunction device displays a first widget on a touch screen and detects a first gesture on a settings icon on the first widget. In response to the first gesture, the device displays user-adjustable settings for a plurality of widgets, including settings for the first widget. The device detects one or more additional gestures to change one or more settings for one or more widgets in the plurality of widgets. In response to the additional gestures, the device changes one or more settings for other widgets, including changing one or more settings for a respective widget other than the first widget. Upon detecting a widget selection gesture and a finishing gesture on the touch screen, the device displays a second widget in the plurality of widgets other than the first widget.

Abstract: In accordance with some embodiments, an electronic device is described. A user interface is displayed while detecting an incoming call from a first phone number. In response to detecting the incoming call and in accordance with a determination that the first phone number for the incoming call does not correspond to an entry in a contact list, the first phone number corresponding to the incoming call is displayed. In response to detecting the incoming call and in accordance with a determination that the first number for the incoming call corresponds to a first entry in the contact list, a name associated with the first entry and/or a graphic associated with the first entry is displayed, without displaying the first phone number.

Abstract: The present disclosure generally relates to managing phone calls. In some embodiments, an electronic device with a touch screen displays a phone call user interface which includes informational items associated with phone calls, such as an add call affordance. In some embodiments, when the electronic device receives a request to initiate another phone and displays an additional user interface that includes a merge call affordance that replaces display of the add call affordance.

Abstract: A portable multifunction device displays a first widget on a touch screen and detects a first gesture on a settings icon on the first widget. In response to the first gesture, the device displays user-adjustable settings for a plurality of widgets, including settings for the first widget. The device detects one or more additional gestures to change one or more settings for one or more widgets in the plurality of widgets. In response to the additional gestures, the device changes one or more settings for other widgets, including changing one or more settings for a respective widget other than the first widget. Upon detecting a widget selection gesture and a finishing gesture on the touch screen, the device displays a second widget in the plurality of widgets other than the first widget.

Abstract: A portable electronic device displays a plurality of icons (e.g., graphical objects) in a region in a touch-sensitive display; detects a predefined user action, with respect to the touch-sensitive display, for initiating a predefined user interface reconfiguration process; and varies positions of one or more icons in the plurality of icons in response to detecting the predefined user action. The varying includes varying the positions of the one or more icons about respective average positions.

Abstract: A portable electronic device with a touch screen display for photo management is disclosed. One aspect of the invention involves a computer-implemented method in which the portable electronic device displays an array of thumbnail images corresponding to a set of photographic images. The device replaces the displayed array of thumbnail images with a user-selected photographic image upon detecting a user contact with a corresponding thumbnail image in the array. The user-selected photographic image is displayed at a larger scale than the corresponding thumbnail image. The portable device displays a different photographic image in replacement of the user-selected photographic image in accordance with a scrolling gesture. The scrolling gesture comprises a substantially horizontal movement of user contact with the touch screen display.
