According to Nokia’s vice president of smart devices, Jo Harlow, after Nokia releases its first WP7-based phone, many other smartphones will follow.

“We should be launching new devices in a rhythm that might be every couple of months, every three months, something like that,” Harlow said.

The first smartphones based on Windows Phone were released less than a year ago, but seems like they weren’t that popular, maybe because the biggest smartphone manufacturers used WP only as a “secondary platform” with Android being their main one. Jo Harlow said that WP is going to be the main OS for Nokia, so Nokia will focus mainly on it. Maybe it will really make both the platform and the manufacturer more famous, who knows.

As for now, we can say Nokia already has some influence on Microsoft’s WP. According to Harlow, some of WP’s “gaps” will probably be filled by Nokia’s cloud services. For example, in the countries where some of Microsoft’s services and applications are not available, Nokia’s similar services and apps will replace them.

Harlow also said that Nokia’s WP devices will probably come to the U.S. on CDMA networks, the attitude to which “has changed,” whatever it means.

She also mentioned that Nokia will probably switch to Qualcomm chipsets, since Microsoft required them in WP smartphones.

“You have to have multiple chipset suppliers that allow you to address different levels of performance, different parts of the business geographically given different modem requirements, etcetera. So the starting point is clearly with Qualcomm… we are in the process with Microsoft of defining other chipset suppliers as well,” Harlow said.
