I have been used it on WM before and a new comer in iPhone 4. I am unsure how and what to buy this software as the software on iTunes is fee. I downloaded it and seems working correctly but not a talking dictionary. Is it the basic dictionary free but the talking feature and larger vocabulary are paid components? Can someone point me to the right place explaining the details. What I need is a good talking dictionary in both English and Chinese (Putonehua)?
