Clarification: You must do a restore before you update to 1.1.4. You cannot update a jailbroken phone straight to 1.1.4.
I also suggest that you sync once before you do a restore (so the back-up that is created when syncing is up-to-date), and also - back up your CAMERA ROLL - The two times I've done a restore, I lost my camera roll, but luckily remembered to back it up the 2nd time.
I've also heard a few complaints with regards to Ziphone 3.0 - and many feel Zibri is a thief, so it is suggested that you use
iLiberty+, which does the very same thing as Ziphone.
