Game is over,  for most of the new individul iPhone developers. Creating a “cool” app and waiting for the money to coming? It is not going to happen, unless: you developed a extraordinary app, and you knew markeing extremely well. There are too many app in the store right now. It become a very clouded market.  This was one of the biggest dream which lured lots of people to become iPhone developers.  

On the other hand, the job market  for iPhone developers  from corporation, startups are increasing. So if you cannot release a top iPhone app, go ahead find yourself a good job.
