The number of jailbreak utilities for iPhones and iPod Touches with the latest iBoot is dramatically increasing. All of them are FAKE. Some of them will fill your computer with viruses, which is not good.
gull1hack, spartanbr3ak, br0k3n_appl3 are just some of these new programs that in one way or another deceive the user and then run malicious code. We therefore ask you to stay away from ANY such software. Some time in the future GeoHot or DevTeam will release new jailbreak and unlock software. Other than that is fake and dangerous. Install only programs you trust or the ones recommended by iPhoneRoot.
