According to an article in today's Times of India, some 60% of India's Blackberry users are based in Bangalore. That's the Bangalore Public Utility Building, where I am sure some Blackberry users work.
This is based on units sold, since BlackBerry first entered India a year ago this month.
Runners-up are Delhi and Mumbai with a little more than a 10% share each. Chennai is right at 10%, while other cities, mostly Pune, Hyderabad and Calcutta, sshare the remaining amount.
