Yahoo has launched a new app for iPhone. It is called the Yahoo Sketch-a-Search. As the names implies, use your finger to circle the area where you would like to receive information and it will retrieve them.
However, the data is only in US, and limited to Restaurants and Cafe. It will slowly roll out to other countries. I wonder when Singapore’s information is going to be inside this apps database. BTW, Yahoo is also thinking of rolling out this software for Android and other platforms.
