ah thats just a startup image. nothing special. the only way to get walkman player on it = flashing to w880i but i wouldn't recommend it because your camera will be fucked and probally some other stuff to. i would just leave it a k800i and perform a few patches on it (altough i dunno what CID you have) you can flash the menu with new icons and even a different layout. but you will never have a proper functioning k800i with flash
