Blackberry maker Research in Motion — which just reported its not-so-hot fourth quarter results — is claiming to be unfazed by Microsoft's pending Windows Mobile 2005 release, which some are calling a "Blackberry killer." Windows Mobile 2005, code-named "Magneto," is based on Windows CE 5.0. Magneto details have been leaking to the Web for months. Magneto is expected to deliver a number of new user-interface improvements; support for ActiveSync 4.0, which will provide for the synchronization of Outlook with photos; WiFi support for Smartphones; and VOIP support via WiFi, according to various Web sites.
