Today I got an answer from the SE support. W890i supports flash menus. The are also original flashmenus, but they are not so spectaculare as the others. The reason, why the other flashmenus dont work, is because of the icons. The icons are for the old menu, but in the w890i is a new menu. It means the icons and the topics are not the same as for example at k800i. The most flash menus which are avaible in internet are for 240x320 k800i.
The only one posibility is to extract the original menus from phone and then change the icons or the design of the menu. It means DOING BY SELF.
May be is anybody there, who is creating his own flash manus for w890i?
Many thanks!
