Bored of looking at the same Android ICS lock screen? Depending on your device some builds of Android enable you to customise the lock screen with widgets that display information like the weather and your next calendar events. To do that select App Drawer > Settings > Lock screen here there should be options for Owner info, Weather and Calendar*. Tap each one to see the options, for weather you may need to manually select a location and the calendar can have a number of future events listed.
*Due to the open nature of Android certain manufacturers may remove or alter default settings.
