Apple just reported September quarter results, and they’re below Wall Street’s expectations for the first time in a long time.

Weaker-than-predicted iPhone sales ahead of the iPhone 4S launch seemed to do Apple in. As a result, revenue and profits both missed the Street’s mark. Overall revenue growth fell to 39% year-over-year, from the low-80%s the prior two quarters.

Meanwhile, iPad and Mac shipments were the main strong spots during the quarter. And Apple has already guided toward a big December quarter, predicting — probably conservatively — $37 billion in revenue.
