If that doesn't work, I posted more thorough instructions HERE that uses the Wallpaper.bmp. If took me forever to figure it out, so my loss is your gain.
Hi again, i checked out ur instructions, thanks for this. It appears to be a similar process to the earlier versions but i just cant find this wallpaper file anywhere. I have opened the qp_bkg_now.dat file with winrar but wallpaper doesnt appear. All i can find is seperator which is what you used with v2 mobile shell but not wallpaper. I have opened other files such as background.dat but it wont let me, error. i tried qpp_bkg_now.dat etc. all of which are in the mobile shell folder from the phone, can you point me to which dat wallpaper is hidden in? Thanks again.
