A version of Skype made for mobile phones and networks is far from complete due to a lack of compatible handsets and technical issues, its CEO said. The world's largest messaging network had originally intended to have the service available on Nokia phones last year. "We have no publicly available products yet to offer and I can't give you a timetable," chief executive and co-founder Niklas Zennstrom told the Finnish daily Helsingin Sanomat, according to a translation by Reuters.

"It is challenging and is taking much longer than expected," he continued. While the company does have a version for Windows Mobile in Europe, it is not commonly downloaded. Also in the interview, Zennstrom acknowledged that some mobile operators saw the company as a threat, but added Skype was looking into ways to work together with them on new services.
