i have a iphone3g jailbreak but it is not unlock so somebody told me to do these steps – Log in as the Administrator; Perform a backup/sync in iTunes for safety; Check if you have the file QTCF.dll, in C: / Windows/System32. If you dont have, you can download it. Remove any passlocks you may have on the phone. Enable âAirplane Modeâ under Settings Open iTunes and disable all Syncing Unplug your phone/ipod. Download BlackRa1n to the root of your C:/ drive. Right click blackra1n.exe and choose Run As.. then enter the Administrator credentials. Uncheck the âProtect my computer and data from unauthorized program activityâ option. If you see âThis file came from another computer and might be blocked to help protect this computerâ then unsure you unblock it.Click Make It Rain, when prompted, connect iPhone. then it will work, but it is even not working now. if you know other trick other than this suggest me??
