Out of beta and free, Skype today launches its video messaging service across all its major platforms. Previously, video missives were limited to 20 free attempts during early testing, but free on premium subscriptions. You can now send unlimited video messages to your Skype contacts on Windows 8, Windows desktop or Mac, while mobile options encompass iOS, Android and BlackBerry. A Windows Phone version is, however, conspicuously MIA. To remind yourself how it all works, check out our early hands-on here.
