For all the hullabaloo about Skype coming to BlackBerry 10, there wasn't much to show at the Z10's launch beyond a logo. We've got more to work with today -- sort of. A preview version of Skype has indeed popped up in BlackBerry World with voice, video and instant messaging like we've seen on other platforms. However, no one in the general public can actually use it yet: the app requires BlackBerry 10.1, which won't reach the market until the Q10 ships to Brits and Canucks. That leaves Americans and Z10 owners in the lurch for a few weeks, although they can at least see the light at the end of the VoIP tunnel.
