iPhone 5 to Start Production by Next September?

According to BusinessInsider, that iPhone 5 won't start production until September and that this suggests that next generation iPhone won't make it to the market until the end of the year or even early next.

Supporting out comments over the last month, conversations with yet another key component supplier indicates that production for iPhone-5 will begin in September. This is consistent with Avian findings in the supply chain in recent months and we believe the consensus view is moving towards this scenario.

Avian cites "key component suppliers" as the source of the information. They also revive the possibility of a cheaper/lower cost iPhone also in the works, but no new details.
