@ManishVision: Unfortunately, in the 3 years since I recorded the Phone series, that service is no longer available it seems.  This is a common problem on the internet ... things change FAST.

Here's a thread of possible alternatives:

They will not be 100% compatible with the code I wrote in that series ... i.e., the web address and the parameters you pass these web services undoubtedly will be different.  I realize that's not the answer you were hoping for but unfortunately that's all I can offer.

We're re-recording that series of videos (right now I'm preparing the material) and we will not be doing that example, but instead using Bing Maps and the Flickr API to find all photos near your current location.
