Apple won't start taking pre-orders for the iPhone 5 until Friday, but at least one analyst already thinks it's going to be a success. Sterne Agee analyst Shaw Wu recently revised his shipping estimates for Apple's product portfolio. "We are raising our September quarter iPhone forecast to 26 million units (from 23 million)," Wu said Thursday morning. "However, we are raising our December quarter forecast by only 1 million to 46 million (from 45 million) [units] due to supplier checks indicating production constraints on new in-cell touchscreens."

Wu lowered his estimates for the iPad, however, in anticipation of Apple's rumored iPad mini launch next month. "We are trimming our iPad forecast to 16.5 million units (from 18 million) due to supplier checks indicating more conservative build plans ahead of a potential iPad mini, as well as a likely minor iPad refresh with a new 9-pin connector (from 30-pin). Wu also raised his Mac forecast from 4.5 million units for the quarter up to 4.8 million units "due to stronger than expected MacBook Air and MacBook Pro momentum."

The analyst estimates Apple will report $36 billion in revenue for the September quarter and $8.65 EPS. That estimate is up from $34.5 billion and $8.73 EPS from earlier reports.
