Spend the money/buy a real phone with proper support and you won't have to deal with that.
I just bought this phone (in Zhengzhou, China).
The phone does not work. My lap tops do not recognize it when I connect the phone to my computer and one cannot change or add a new wall paper or change the programed wallpaper that has flowers on it.
I took the phone back to the Dennis Mall in Zhongzhou, where I bought it. But the 15 year old electronics manager (sic) claims the phone works. Even if they were unable to change the wall paper and screensaver themselves.
Makes a great paper-weight!
