Sony Corp. said Wednesday its net profit for the April-June period posted a 20-fold jump to 23.26 billion yen, helped by the firm's mobile phone handset venture with Sony Ericsson Mobile Communications AB.

A stronger yen, however, hurt the consumer electronics giant. Compared with the same period last year, its operating profit fell 41 percent to 9.77 billion yen, while revenue remained almost flat at 1.61 trillion yen.

Excluding currency fluctuations, operating profit grew 27 percent and revenue rose 5 percent, the company said.
