Mozilla on Monday announced the first alpha release of its Fennec mobile browser for the Windows Mobile 6 operating system. This alpha is available only on the HTC Touch Pro from Sprint. Versions for other smartphones will be unveiled later. While Microsoft continues to upgrade the sixth version of its mobile OS, it is expected to release a new edition, Windows Mobile 7, next year. Mozilla first tested Fennec on Maemo, a software platform developed by Nokia with various open source projects, including Debian and Gnome.
