i have a 3GS on OS 4.0.1 with 5.13.04. currently its jailbroken and unlocked. i am trying to restore it to 4.3.3 and then re jailbreak/unlock. however the restore is not working with itunes. i heard that its possible itunes is no longer authorizing upgrades to 4.3.3 in an effort to force u to upgrade to 4.3.5 or 5.0 or something. is this true ? if so is there any way around this ?
