Nokia and iPass are developing client software for Nokia dual-mode phones that will let users connect to public Wi-Fi hot spots worldwide, the companies announced Wednesday.Through partnerships with hot spot operators, iPass offers access to about 50,000 hot spots around the world through a single account, according to the Redwood Shores, Calif., company. Client software for using the iPass service is already available for Microsoft Windows and Windows Mobile operating systems, as well as for Apple Computer\u2019s Mac OS. The companies initially will develop a client for a set of handsets with cellular and wireless LAN capability that are based on the Nokia Series 80 and Series 60 software platforms. They expect to deliver software for the Nokia 9300i and 9500 by summer, which typically means June through August. By the end of this year, they plan to make available clients for Nokia Eseries devices, a line of business phones announced last October. In addition to hot spots in airports, hotels and other locations, iPass provides Internet connectivity via dial-up, ISDN and wired broadband connections. The service includes security enforcement and centralized policy-based management.-Stephen Lawson, IDG News ServiceCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
