I just read about an event called the Mobile Application Conference India 09 which is going to take place on 31st October 2009 in Bangalore. It will be a one full day event with opportunities to meet developers, entrepreneurs, angel investors, venture capitalists, operators and probably everyone that forms a the thriving mobile ecosystem in India.
Although the speaker list is not known as yet, the topics look good and debatable. There would also be a presentations by startups to compete in the Top Startup Competition.
The conference is free, but I believe there are limited seats where your registration would be reviewed before getting the final invite. You can register for the conference on this link.
