Helicopter video
here
Not sure what you mean by "i need some to tell how i install wallpaper and Helicopter to "phone i 8910 O. HD" movie on phone. Where did i find the small HD movie to phone to?" To install wallpaper just browse to any picture in mediabrowser, press 'use image' and select 'set as wallpaper'.
You can copy almost any popular video format to the phone and it will play it, but to save space you can re-size it first. I use Format Factory.
To 'install' a movie just copy it to your mass storage or memory card on your PC.
