Warning issued by phone chipmaker

Wolfson chips
Wolfson makes chips for Samsung and Apple mobile phones

Edinburgh-based chipmaker Wolfson Microelectronics has warned that its orders for October, November and December are worse than expected.

The company said it would usually expect to have received more orders by this stage in the year.

It blamed its failure to get a contract for a new product, which is understood to be Apple's iPhone 3GS. It makes chips for the earlier iPhone 3G model.

Shares in Wolfson fell following the announcement, ending the day 9% lower.

There was some better news though, with Wolfson saying it had won the contract to provide an audio chip to a new mobile phone customer.

The new customer is understood to be Nokia, which has put Wolfson chips in its Twist model, recently launched in the US.

Wolfson is due to release results for July to September on 28 October, which it said was in line with the amount of orders it said it had received when it reported half-year results on 28 July.
