Apple said on Monday it earned $US3.4 billion ($A3.77 billion), or $US3.67 ($A4.07) per share, in the latest quarter, which ended December 26.
In the same period of 2008 it earned $US2.3 billion ($A2.55 billion), or $US2.50 ($A2.77) per share, when it was still deferring iPhone revenue.
Revenue was $US15.7 billion ($A17.39 billion), a 32 per cent jump from $US11.9 billion ($A13.18 billion) in the same period last year.

The earnings report was released after Apple shares gained $US5.32 ($A5.89), or 2.7 per cent, to close at $US203.07 ($A224.98). In extended trading the shares rose $US1.28 ($A1.42) to $US204.36 ($A226.41).
