According to oDesk, a technology outsourcer billing itself as the “leading marketplace and global IT platform for outsourcing technology jobs to certified, freelance, Apple iPhone developers”, demand has risen for iPhone-related positions from 30 to upwards of 140 jobs per month over the past six months.

While the numbers are drawn from internal oDesk records only, such a steep increase is unlikely to be an isolated phenomenon. Nor is oDesk’s sample pool a limited one, since they have representation in over 100 countries worldwide, including major markets like the U.S. and China.

Though some of the growth followed immediately after the announcement of the iPhone SDK availability, the most significant growth came after last July, when the App Store officially opened for business. No doubt the impressive download numbers that continue to come out of Cupertino are beginning to catch the attention of the wait-and-see corporate crowd.

In the spirit of Guy Kawasaki’s Truemors experiment, we challenged ourselves to create a social networking iPhone app – from concept to development to distribution – in 30 days. This includes coding the servers, clients, spatial implementation (PhotoKast is an LBS app), etc. This document is a combination of what we have learned over the last four years in mobile development, and how that was applied to the making of PhotoKast. It is not a How-To guide on coding; it addresses the other parts of development, with an emphasis on design and planning.
