TechRadar has gotten a glimpse of the upcoming new BlackBerry operating system and reports that version 4.6 will use the Ajax Web browser and provide for better page layouts and easier zooming.

The new version is going into the next BlackBerry Bold and Thunder models.

Other upgrades include a Music Sync feature for easier transfer of music and other content, an improved spell checker and enhanced HTML and JavaScript support.

RIM has yet to announce a release date for the new OS but, as the article points out, the new handsets are due out soon, so it can't be too far in the future.
