People who wish to add a carrier logo replacing carriers names (Airtel Vodafone etc) will be happy to hear that Zeppelin has been updated to support iOS 7. The useful tweak can be enabled or disabled from a menu in the Settings app, without a respring required, and comes with over a dozen preinstalled logos to choose.
Zeppelin for iOS 7 is available as a free download on Cydia by adding the repository repo.alexzielenski.com to your sources. The update should also be available soon in the ModMyi repo. Note that this tweak, like any other tweak, will not work with A7 devices.
