Earlier this month, Apple dropped the non-disclosure agreement that prevented iPhone software developers from publicly discussing the details of their work, saying "...the NDA has created too much of a burden on developers, authors and others interested in helping further the iPhone's success."
Developers and would-be developers were pleased, and several shared what they had learned right away.
Prior to this change, Apple announced a series of iPhone Tech Talks for several cities in the US. Now, that program has expanded into the iPhone Tech Talk World Tour. Developers in 24 cities across North America, Europe, India and Asia Pacific can attend workshops like "Introduction to Objective-C and Cocoa Touch" and "iPhone Game Development Technologies."
