On the China Dospy forum, WeChat promised support for the N9, but that was more than half year ago, so I believe they are no longer interested in this platform... Interesting features on Wechat: * Videocall * Moments: like Twitter where you can share pics too, like FB you can create your own page * Voice chat: more convenient than typing an SMS... * Group chat: * Look around/shake/drift bottle: finding people with WeChat nearby so you can send them greetings * Facebook connect I think the company behind WeChat is also developer of QQ messenger.
