What's next for Nokia and Microsoft

Just as Nokia reports a 30 percent decline in cellphone sales, Microsoft is taking the reins of that company's device business to refresh its Windows phone lineup, leaving Nokia to focus on its somewhat lesser-known businesses.

Under its new CEO, Rajeev Suri, Nokia will likely focus on its telecommunications network and in particular, notes CNET Senior Editor Bridget Carey.

Nokia has already relied on its network business for about 90 percent of its revenue.
