this is because after 1.1.1, the jailbreakme.com issue was fixed by apple. if you want your iphone/itouch jailbroken or unlocked, please visit ziphone.org and download his software for jailbraking and unlocking. It is by far the easiest method for such purposes. You just download the program and within 3 minutes i think, you have your phone jailbroken. but first you need to restore to 1.1.4 (yeah, it works even with the most updated software

)
