developers conference

Apple Inc will host its annual developers conference starting June 7, where the company is expected to unveil the latest version of the iPhone.

Hi everyone,
I am a mobile application developer... learning the tricks of the trade would be a better description.. was thinking about attending the Forum Nokia Conference'09 in Bangalore on 7th December.

Can anyone tell me whether its worth attending? Did anyone take part in the previous conferences? What are the prospects for an aspiring budding developer?

Looking forward to some feedback
