Nokia (NYSE:NOK) shares slipped hard this morning after a supplier warned of falling sales, Bloomberg reported. Danske Bank downgraded the mobile phone giant’s stock to “sell” following a drop in shipments of older Symbian phones, according to the report.

STMicroelectronics NV (NYSE:STM), Europe’s largest manufacturer of semiconductors and a supplier to Nokia, announced yesterday that it expects first-quarter revenue to decline as much as 10 percent from the previous three months due to weak sales at the ST-Ericsson AB joint venture.

In a fourth-quarter report yesterday, ST-Ericsson (NASDAQ:ERIC) said it expects sales and operating results to “continue to be challenging in coming quarters” thanks to a short-term decline in new product sales with one of its largest customers. ST-Ericsson did not disclose the name of the customer.
