I get by with English and broken Hinglish in Pune and Mumbai. Those are the cities with internet and money. That wouldn't work so well in smaller cities, but those are also not the places I'd target if I were building a business.

As for the south, in my limited experience the same is true. English works fine in Bangalore if you restrict your conversations to upper middle class people with good internet and money to spend.
