Apple deal hits revenues at Wolfson; In brief.

THE loss of the Apple iPhone 3GS contract continued to haunt chip designer Wolfson Microelectronics as it warned second-half revenues were under pressure.

Wolfson, whose components are used in products such as flat screen televisions, games consoles and TomTom car navigation systems, said backlogs of work for the fourth quarter had not built up as quickly as usual, while visibility on customer demand was poor.

But the Edinburgh-based firm said a recent design win, thought to be the new Nokia Twist mobile phone in the US, was a "very encouraging" sign of customer interest in its new product lines.

Wolfson also said it was "increasingly confident" of strong revenue growth in 2010.
