Good day! For those having "Spamming AT, waiting for response", i know your pain. here are my steps in jailbreaking with ziphone: 1) Recovery mode (itunes logo + plug screen) 2) Unzipped ziphone 1.0. (yeah, the first version) 3) Open ziphoneGUI.exe, tick Jailbreak and verbose checkbox. 4) Click START. restart - NO CHANGES! - Restart - Viola! installer.app lives!! YATTA! next thing to do is install the BSD subsystem BEFORE installing other apps... Specs: 8GB iPod Touch (OOB firmware 1.1.2) iTunes 7.6 Windows XP sp2 Ziphone 1.0 hope it would help others. see the whole story here.
