Nokia added three new siblings to its upcoming family of smartphone offerings at Nokia World on Tuesday, adding a business-oriented handset and two consumer-oriented devices to its previously announced flagship N8 phone. The E7, C7 and C6 are expected to roll out before the end of the year, but it’s not clear whether that launch is worldwide or if the phones will be available for the holiday shopping season. Nokia did not respond to a message seeking comment by deadline for this article.
