HTC Mazaa is a smartphone that I learned the details since April, and he passed in turn from escape, the actual pattern and finally phone which will not be released. It seems that this is a model intended for developers and that will be offered as a prize for the winners of the competition WPAppItUp.
How about Mazza, it is a Windows Phone 7 Mango, running the build version of OS-7720. The new HTC Mazaa recalls the design Trophy, a phone launched last year on board with Windows Phone 7. The images you see in this article published by one of the developers who won a model Mazaa.
The same developer claims that Terminal is faster than HTC HD7, and if you want such a model, you can learn that Microsoft has announced that the phone is still just for developers.
