Jailbreaking your newly upgraded, previously jailbroken, iPhone with ZiPhone will result in a loss of application icons on your Springboard.

I will update this post for the latest information I find on the 1.1.4 jailbreak process.

So far:

• Applications seem to stay installed
• No icons for installed applications visible on Springboard
• Uninstalling applications works
• Installing new applications work, shows icon on Springboard

Note: Zibri, creator of the ZiPhone jailbreak, is letting users know that they should not upgrade or jailbreak 1.1.4 until he has had the chance to fully test!

Update: Zibri announced that the Jailbreak will work with 1.1.4, but he needs to make a few tweaks first. He should have a new version out within the next 2-3 days.
