-----Note: Version 1.1-1 of Zeppelin, released on 28/01/13, resolves the bug reported by this thread.
iPad Jailbreakers who use the Zeppelin tweak for custom carrier logos please beware!
The latest update, V1.1 is seriously broken on the iPad and will cause some extremely strange behaviour. If you have V1 installed, do not update to 1.1 via Cydia.
Several members, including myself have already fallen foul of it e.g here - Some update from Cydia totally destroyed the layout, and here - Can I backup a a jailbroken iPad with iTunes
If you have updated to 1.1, then use Safe Mode to remove it if you experience issues with the iPad behaving like an iPhone - HOW TO - Use Safe Mode to maintain a stable jailbreak
I have been in touch with the developer via twitter, and whilst he acknowledges the issue, he has provided no ETA for a fix.
Symptoms manifest themselves when you reboot the iPad. These include small icons, missing dock, and a tiny iPhone keyboard, as can be seen in the screenshots below. The issues can be temporarily resolved by respringing the device, but it will happen again on a reboot.
For the time being, the tweak will not be featured on our Ultimate List of Jailbreak Tweaks thread. Stay tuned to the forum. We'll be sure to post an update if we hear any news.
