HELSINKI, Finland (AP) — For Nokia, it comes down to this: Is Microsoft’s new phone software going to get it back in the smartphone race, or is it going to be too late?

After being the top seller of cellphones in the world for 14 years, Nokia failed to meet the challenge when Apple in 2007 introduced the dazzling iPhone that caught the imagination of design-conscious customers and rattled mobile markets.

The Finnish company hit a downward spiral that has led to shrinking sales and market share.
