i am wondering what it will be when honami comes, there are rumors about new interface.
The first set of screenshots appear that of "Go Launcher" even the default wallpaper is there...dont know if they indeed are the actual screenshots of the leaked device
The green colored 'phone' icon looks more like Samsung/LG's cartoonish UI. No way Sony is going to use such ugly icons in its UI. Moreover, the pics shown here must be taken from a phone which is using some sort of launcher.
There are elements from Samsung TouchWiz in the 'leaked build' screenshots (The icon for the phone dialer in 'leak' VS real Sony UX phone dialer; TouchWiz keyboard; Samsung's Game Hub). Oh well...
