Where can I get a copy of the uphone SDK so that I can play with cocos2d-uphone?
You can download uphone sdk from here http://dev.uphoneapp.com/doc/index.xhtml?type=0110But CHN only
Where can i get technical information e.g. architecture of Wophone in English?
So sorry. WoPhone, the sponsor of cocos2d-x, only facing the Chinese internal market, and has no English documents yet.I guess it may open to global developers at the end of 2011, but I cannot promise that.
