4 . The method of claim 1 , further comprising:

maintaining the mobile device in the first state continuously when the contact upon detection, does not correspond to the predefined icon, or the rotation or the movement upon detection does not correspond to the predefined gesture.

5 . The method of claim 4 , further comprising:

while the mobile device is in the first state, preventing the mobile device from performing a predefined set of actions in response to detecting any contact with the touch-sensitive display that does not correspond to the predefined icon, or in response to detecting any rotation or movement with the motion sensor that does not correspond to the predefined gesture.

6 . The method of claim 1 , wherein the movement upon detection by the motion sensor is a horizontal movement or the rotation upon detection by the motion sensor is a vertical rotation.

7 . The method of claim 1 , wherein the motion sensor includes at least one of a gravity sensor, a gyroscope or a magnetometer.

8 . A method of controlling a mobile device configured with a touch-sensitive display and a motion sensor, comprising:

detecting a contact with the touch-sensitive display;

selecting a widget in a starting page and dragging the widget when the contact starts corresponding to the widget;

detecting a rotation or a movement with the motion sensor;

transitioning the mobile device from the starting page to a destination page according to the rotation or the movement upon detection, wherein speed of the transition from the starting page to the destination page is in proportion to speed of the rotation or speed of the movement; and

moving the widget from the starting page to the destination page when the contact terminates in the destination page.

9 . The method of claim 8 , further comprising:

maintaining the widget in the starting page when the contact does not terminate in the destination page.

10 . The method of claim 8 , wherein moving the widget from the starting page to the destination page when the contact terminates in the destination page comprises: moving the widget from the starting page to the destination page when a continuous contact is maintained between the time the contact starts corresponding to the widget and the time the contact terminates in the destination page.

11 . A mobile device, comprising:

a touch-sensitive display;

a motion sensor;

a memory;

one or more processors; and

one or more modules stored in the memory and configured for execution by the one or more processors, the one or more modules including instructions to perform a plurality of tasks, the tasks comprising:

detecting a contact with the touch-sensitive display while the mobile device is in a first state to determine whether the detected contact corresponds to a predefined icon;

detecting a rotation or a movement with the motion sensor while the mobile device is in the first state to determine whether the detected rotation or the detected movement corresponds to a predefined gesture; and

transitioning the mobile device to a second state when the detected contact corresponds to the predefined icon, and the detected rotation or the detected movement corresponds to the predefined gesture.

12 . The mobile device of claim 11 , wherein the first state is a user-interface lock state and the second state is a predefined state.

13 . The mobile device of claim 12 , wherein the predefined state is a user-interface unlock state.

14 . The mobile device of claim 11 , wherein the tasks further comprise:

maintaining the mobile device in the first state when the detected contact does not correspond to the predefined icon, or the detected rotation or the detected movement does not correspond to the predefined gesture.

15 . The mobile device of claim 14 , wherein the tasks further comprise:

while the mobile device is in the first state, preventing the mobile device from performing a predefined set of actions in response to detecting any contact with the touch-sensitive display that does not correspond to the predefined icon, or in response to detecting any rotation or movement with the motion sensor that does not correspond to the predefined gesture.

16 . The mobile device of claim 11 , wherein the movement upon detection by the motion sensor is a horizontal movement or the rotation upon detection by the motion sensor is a vertical rotation.

17 . The mobile device of claim 11 , wherein the motion sensor comprising at least one of a gravity sensor, a gyroscope or a magnetometer.

18 . A mobile device, comprising:

a touch-sensitive display;

a motion sensor;

a memory;

one or more processors; and

one or more modules stored in the memory and configured for execution by the one or more processors, the one or more modules comprising instructions to perform a plurality of tasks, the tasks comprising:

detecting a contact with the touch-sensitive display;

selecting a widget in a starting page and dragging the widget when the detected contact starts corresponding to the widget;

detecting a rotation or a movement with the motion sensor;

transitioning the mobile device from the starting page to a destination page according to the rotation or the movement, wherein speed of the transition from the starting page to the destination page is in proportion to speed of the rotation or speed of the movement; and

moving the widget from the starting page to the destination page when the contact terminates in the destination page.

19 . The mobile device of claim 18 , wherein the tasks further comprise:

maintaining the widget in the starting page when the contact does not terminate in the destination page.

20 . The mobile device of claim 18 , wherein the task of moving the widget from the starting page to the destination page when the contact terminates in the destination page comprises: moving the widget from the starting page to the destination page when the contact continues between the time the contact starts corresponding to the widget and the time the contact terminates in the destination page.

21 . A method of controlling a mobile device configured with a touch-sensitive display and a motion sensor, comprising:

detecting a contact with the touch-sensitive display while the mobile device is in a user-interface lock state to determine whether the contact corresponds to a predefined icon;

detecting a rotation or a movement with the motion sensor while the mobile device is in a first user-interface lock state to determine whether the rotation or the movement corresponds to a predefined gesture, wherein the predefined icon moves along a bar according to the rotation or the movement;

transitioning the mobile device from the first user-interface lock state to a second user-interface lock state when the contact is continuously maintained, and the rotation or movement corresponds to the predefined gesture; and

transitioning the mobile device from the second user-interface lock state to a predefined state when the predefined icon moves to the end of the bar according to the rotation or the movement.
