First announced at BlackBerry Jam Asia as coming to BlackBerry 10, the Seina Weibo is now in BlackBerry World. This one may well only be of interest to certain regions as the service is currently one of the most popular social networking sites in China. In fact, it has over 100 million posts a day!

Sina Weibo is kind of a cross between Twitter and Facebook and clearly extremely popular in China. The application has been built natively for BlackBerry 10 and if you missed our demonstration video from BlackBerry Jam Asia you can catch up here.

Will Weibo take the world by storm? Only time will tell, but at least us BlackBerry 10 users can now get in on the action. If you're not seeing it in BlackBerry World just yet please check back later - it's only just gone live.
