Hi all. I'm running a jailbroken iPhone 3G 4.0 without Winterboard. Then I tried installing a custom dialer; I followed the instructions given on several YouTube vids but it dodn't work the way I wanted so I started messing about with it (I did make BACKUPS, but they didn't help eventually). * I changed stuff on two folders: and What I did was attempting to Drag and Drop modified .png files I got from the net to these folders, replacing them over the original files. For some reason, the app got screwed up. Now I see the icon on the springboard, but when I click it it would just open for a split-second (still blank board) and shut down immediately. Can you think of a way to help me? btw- I tried downloading the stock-apps folder and copying the MobilePhone.app folder into mine, but it doesn't work. I guess it's not 4.0.
