Microsoft and Nokia made an agreement under which Nokia's upcoming 60 series will have Windows live services embedded. Instant Messenger and Hotmail are two major Windows Live services.
The service will be free of charge initially.Under the deal, Nokia will start offering Windows Live Hotmail and Windows Live Messenger on its most powerful Series 60 handsets this year. Later in the year or early next year, the services will be made available on Series 40 phones.
Berkowitz said Microsoft will continue to develop versions of Windows Live services for its own Windows Mobile operating systems as well as slimmed-down WAP (Wireless Application Protocol) versions that can run on a wide array of phones.
As for whether it would develop any sites tailored for Apple's iPhone, Berkowitz quipped, "If the iPhone were ever to get any distribution, maybe."
He added that the company will go where the marketplace and its customers demand. "Our best place to invest is where the reach is," he said. "Nokia is a great example of that."
The latest deal has been in the works for more than a year, the companies said.
"It's taken a bit of time and a bit of learning on both sides," said Nigel Rundström, Nokia's vice president of multimedia experiences.
