I just restored my iPhone 3G and updated. I was running a jailbroken 3.1.2 and upgraded to 3.1.3. I restored and then updated obviously. While my phone was jailbroken, I downloaded Cydia apps that let me change the AT&T logo by the service bars and another to give me a percentage by the battery. All of my Cydia apps are gone, yet I still have a changed AT&T logo (it says my name now) and my percentage bar is still there. Why didn't these get deleted?
