Working Airtel backquery for airtel maharashtra free gprs

I know that all twitter backqueries are blocked in various states of India but today the below backquery is working in Maharashtra. Its true, it may not work in other states but its working in maharashtra. See my post on backqueries, for knowing other backqueries on twitter. I think all of them will work in the land of dreams. http://a3.twimg.com/
