Thanks guys.... I have done some more redesigning.
1> I have redesign the GUI - Bigger buttons,
2> shows your location ( a small green flag in the center).
3> You can search an Address, ( I am not sure why the local business is now stopped. example... Nike store in San Fransisco, when I was testing it locally .. it was working fine.)
4> you can tap on the flag or marker to see the street view.
5> clicking the street View will show the street view of the center of the map.
6> bigger fonts and buttons for search box....
7> Panning in the map as well as Street view works faster...( I guess )

Future development that I am planning....

1> Fix the searching of local POI. so you can search all the pizza place near your location and put one of them as a destination for driving direction. an Njoy hot pizza.

2> Refresh own location every 5 sec or so... ( this will help while driving, you will be able to see the map updates your position. and zooms in as you get closer to a location )

3> Driving direction in List view.

as I am testing on the server it self the application may be down or give you some other results for some more days. plz bare.

One more thing I am in US so can anyone from other part of the world share their experience as of accuracy and all. will be much helpful. I will provide the source code to anyone from coming Monday. Let me know if anyone needs it.
