Ziphone 2.2. GUI.

Is it true that the GUI is buggy. I am gonna use the normal one on command prompt but is there a difference.

Depends what you are using it for. To activate / jailbreak / unlock you are fine, to downgrade bootloader is a bit dodgy IMAO.

anything to do with activate jailbreak unlock ziphone 2.2 is very good

I've been using the cmd line ZI 2.0 without issues... have downgraded many bootloaders with no problems.

I always use -v option.

I don't know that 2.2 offers any new functionality.

use hacx iphone unlock gui, its far better..
it has backup & restore on it.
