I had jailbroken my iPad 2 5.1 with absinthe and it was running fine. I had winterboard installed on it, though I just used a zeppelin logo and nothing else to customize my pad. I had restarted it before too but today it was showing an iphone like interface with no dock, full screen notification bar, iPhone coloured battery icon etc. Settings were inaccessible and app icons got small and were arranged in stack of 4 by 4. After multiple restarts it's still the same. I have put my device to update (and restore) via itunes and it's still 2 hours before the firmware gets downloaded. Any help??

You have installed a tweak which is not ipad or 6.1 compatible. Use Safe Mode to remove it. No need to restore.

HOW TO - Use Safe Mode to maintain a stable jailbreak

An old version of zeppelin will cause this issue. Only the latest one works on iPad.
