HTC Hero :: Way To Get Phone Ocean Wallpaper?

I have a Hero, and have to send it back to Orange because the fascia is damaged. Orange send me a new Hero, exactly the same model, etc. I root the phone, set up some of my apps and notice that THIS Hero is sporting the blue wallpaper (the one with the ocean and blue sky). I cant find this anywhere on my phone, and never came across it on the old Hero. Does anyone know where this wallpaper came from, and where I can locate it?
