I JBed my iphone a while back, and used Customize to apply my wallpaper to the home screen background. At one point I used iphone browser and dropped the picture I liked as the 'wallpaper.png' file and replaced the default one in the process. Since then, I cannot change wallpaper anymore. It has not effect, whatever I do and Customize crashes at boot up. I have upgraded my iphone, I have even restored it, re-JB etc. but the wallpaper stays the same. Now if I use iphone browser, I cannot find the location of that default wallpaper.png in the new filing. Can someone help, either way...where is the wallpaper.png so I can just drag and drop a new pic or a better permanent fix? Many thanks!
