Know what this spider is?

I took this photo yesterday. This spider was on a  really impossible place by a roadside, on a web spun among some grass. However I tried, I couldn't make a well focused shot at this one. I couldn't bring myself to discard all those images though. I chose one of the least crappy ones, had a go at it with Picnik's auto fix tool. Then I did some tweaks to the background with my favorite Gimp, and here's the result. I've uploaded this image here on Lakdasun forum for possible identification. Pleas do tell me if you know what this species is.
