After weeks of searching and trying different methods, I finally have found a method that works! First you will need to install a free package from Cydia called "Verizon Carrier Retina iOS 5" After that you will need to SSH into your phone to System/Library/Carrier bundles/iPhone/Zeppelin_US.bundle Edit the carrier.plist file. Look for the line: <key>StaticNATType</key> <integer>448</integer> In the next line insert: <key>StatusBarImages</key> <array> <dict> <key>AllowPrefixMatching</key> <false/> <key>CarrierName</key> <string>Verizon</string> <key>DefaultImage</key> <string>Default_CARRIER_Zeppelin_US.png</string> <key>FullScreenOpaqueImage</key> <string>FSO_CARRIER_Zeppelin_US.png</string> <key>StatusBarCarrierName</key> <string>Verizon</string> </dict> </array> **Keep this code handy, as the author claims you may need to re-edit the plist when you reboot your phone** After that go to var/private/stash/themes.x/Verizon Carrier Retina iOS5.theme/Bundles/com.apple_US make sure you have 3 copys of the carrier logo of your choice, and rename them exactly as the pngs in this file, then simply delete the 3 pngs in the file, and replace them with yours. Ensure you have the theme selected in Winterboard, Respring, and your custom carrier logo should appear Enjoy! Let me know if you run into any problems, I'll try to help the best that I can.
