First of all, yes, there is such a place as Nokia World. Since Nokia is a company all about mobility, it makes sense that Nokia World is a moving location. This year it will be located in Stuttgart, Germany. It's essentially a place for people passionate about mobility to talk about it, try out new things, and more.
So how do you get free tickets to Nokia World? Simple. Just enter Nokia's Calling All Innovators competition, a program where mobile and web app developers submit apps and ideas for use on Nokia devices. If you've got an idea or app for Internet Innovation, Flash, Emerging Markets and Mobile Necessities, or Apps on Maps for Nokia products, check out the competition before June 30th - that's the last day to submit.
If you're a finalist, you'll find out on August 17th and get a free trip to Nokia World in September.
