Apple is ramping-up production for its keenly-anticipated iPhone, with Tawan's Nanya Printed Circuit Board Corp. confirming its boards have been certified for use in the product.

Citing "sources", EMSNow claims Nanya will begin providing the first batch of circuit boards for the new Apple multimedia device in "early April".

The company isn't the only component supplier Apple will use, but does expect to get 30 per cent of the orders for circuit boards, the report explains.

This will drop a healthy NT$300-400 million onto Nanya's bottom line, the report explains, boosting profits this year.

Apple expects to sell ten million iPhones within the first 12 months of the release of the product. Over one billion handsets shipped in 2006.
