Whenever you want to display your location from the Google Map, this is a good candidate. It uses the Latitude and Longitude value to identify the location on the Google Map. If you do not know your location latitude and longitude value, you can simply find it out from http://itouchmap.com/latlong.html.
This app supports another key factor, information box. The information such as Company Name, Address, or whatever you want to show, you can put them into the app part property "Information". This property supports basic text style, such as bold, italic or line break.
Furthermore if you want to make cosmetics changes, you can play with the app part property "InformationBoxStyle".
Sometimes, you do not really want to position your location at the center of the Google Map, for example, if you want to pan the map a little downward to give more space to the Information panel, you can give a positive value to the app part property "MoveCenterDownLatitude", this will pan the Google Map downwards.
OK, have fun!
