I was going though Cydia and I found something called Supreme Preferences, and after I installed that I noticed that my at&t logo disappeared. I had the AT&T Carrier Logo from Cydia, and it's completely gone. The Wi-Fi / EDGE logo just moved into it's spot, and is right next the signal bars. I'm not sure whether supreme preferences did anything, but I also installed Dock, but I don't think that's what caused anything. Has this happened to anyone else? I also uninstalled my custom logo, and it's still not there.
