3GS with background Image

[SKANLEZ]

I just got my 3G-S today. My previous iPhone was jailbroken and I put a picture as my background. So basically when I call it will show the picture I inserted (using). Long story short, my 3GS shows the picture when calling out. But as when on the home screen it shows the stock background (black). How do I remove that picture? Please help.

Is it your current background on the lockscreen? Because that's the expected behavior.
