Jailbroke 3G iPhone today.
Installed Customize from Cydia then changed the theme to Buuf2.

Everything changed except the background, not the lock background but the wallpaper when the iPhone is active.

I tried to change back to default theme and now everything has changed back except the dock and active wallpaper

Any ideas?

Incase anyone else has this problem

Its Customize, just use Winterboard instead, works perfectly

Now I just need a fix for maps
