After dropping the NDA that served as an awkward communication barrier between iPhone developers, Apple has now launched a worldwide tour of presentations covering the iPhone application development tools and related technologies.

The free events, which start later this month and continue through December, will send Apple engineers and technology evangelists across the US, Europe, India, Asia and Australia to meet with developers and provide them with expertise in code optimization, user interface design, game design, web and custom apps for the enterprise, and to answer general questions about mobile software development.

Developers can register to attend one of the tech talk events online, which will be held in the following cities:

North America
Oct 22 San Francisco
Oct 24 Los Angeles
Nov 03 Austin
Nov 05 Chicago
Dec 02 New York
Dec 04 Toronto
Dec 09 Seattle

Europe

Oct 24 Munich
Nov 03 Amsterdam
Nov 07 London
Nov 10 Berlin
Nov 11 Madrid
Nov 14 Copenhagen
Nov 17 Zurich
Nov 19 Rome
Dec 08 Stockholm

India
Nov 24 Bangalore
Nov 27 Delhi

Asia Pacific
Oct 30 Tokyo
Nov 04 Singapore
Nov 10 Hong Kong
Nov 19 Sydney
Nov 21 Melbourne

In the US, the events are scheduled like a mini-WWDC, with three session tracks featuring presentations such as Introduction to Objective-C and Cocoa Touch, Advanced UIKit and Device Features, iPhone User Interface Design, iPhone Game Development Technologies, Maximizing Your Application's Performance on iPhone, and Submitting to the App Store using iTunes Connect.

The third track focuses on corporate development, including the sessions Using Advanced Web Technologies on iPhone, Integrating iPhone with IT, and In-house Application Development for iPhone.

In other regions, a simplified session outline will be presented. The sessions are free to attend, but Apple warns that space is limited. At WWDC, individuals pay around $1500 to attend, but Apple still ran out of space at the Moscone West convention center this year.
