Where It's At starts up with a list of all available services displayed in a table along with a small image that helps identify the service.

To search for a service with a keyword click in the search box and type the word you wish to search for and press Search.

Where It's At will search for the keyword in the service providers name, the service name and the full service description.

To just show services that have locations near to your current location press the Nearby button in the top left of the screen and the list will reload.  To revert back to the full list press the Nearby button again.

To refresh either the full list of services or the nearby list to see if any new ones have been added simply 'pull' the list of services down until you see the 'Release to refresh' text and then let go.  The service list will then be updated.

Click on the details arrow on the services list to see more details about this service including who is providing it and a URL to click on for more details.

Click on the service name in the list of services to show a map view of all the locations in that service.

You can rotate the iPhone to show the map in a Landscape view if you wish.  (Note that all pages can be rotated so if it helps to see the information then feel free).

Press the cross-hairs button in the lower left corner of the screen to show your current location.  

'Pinch' the map to zoom into a particular area, and use the 'radar' graphic next to the cross-hairs to zoom back out to show all the locations.

Tap on a map pin to show the name of the location.

Press the details arrow on the map label to see any attributes, or details, for the location.
