IPHONE 3G 16GB shows lock symbol and itunes usb connected(locked)

Unforunatly when you hook the phone up to Itunes it updates and relocks itself. This is Apple and At&t's way of keeping it locked. You are going to have to get the phone unlocked again.

Can't restore to my iphone from 2.0 to 1.1.4

Try this tijanotu:

You will need these files/program:

1. Ziphone 3.0 program

2. Ziphone Firmware Files 1.1.2, AND 1.1.4. To get these files open Ziphone 3.0 then Click Help and Support, then middle box on top of page Web Links Firmware Files 1.1.2 and 1.1.4 (to make it easier to find I always save everything to the desktop)
3. Kiphone

Not sure if all these steps are needed for success, I am just putting it all down becuase this is exactly what I did to get my cell signal back.

First, I uninstalled itunes 7.7.

Then I downloaded and installed itunes 7.5. At this point you will have to rename your itunes libray folder. Instructions are here:

Next I downgraded the iphone to 1.1.2 using the link above.
Downgrading steps:
Connect phone to computer
Open Ziphone 3.0
Click on Prepare for Upgrade (this will put iphone into DFU mode)
Now you have to restore using itunes 7.5 (which will open up as soon as the iphone goes into DFU mode.)
In itunes hold down SHIFT key (FOR WINDOWS) while pressing RESTORE. This will allow you to browse for the firmware file 1.1.2 you previously downloaded. Click on the 1.1.2 restore file and hit OPEN. This will begin the restoring process.
You will probably get an error code noting the restore wasn't successful. Ignore this unless the error code number is in the 1600's.
After this I tried to jailbreak my iphone using Ziphone 3.0 but wasn't successful so I:
Repeated the restore process but his time restoring to 1.1.4. Got the same error saying that restore wasn't successful, which I ignored.
Then I closed itunes, went into Ziphone 3.0 (iphone still connected to computer) and clicked on Do it all!
Jailbreak worked fine except I still had no cell signal.
To fix this I went to:
Iclarified, (the BEST iphone website *******!!) Got Kiphone patch (see Number 3 above) installed it and got my cell service back.

My iphone is not working with my sim

Your iPhone is probably still locked. You first need to unlock it. To do so, go to and type in ZiPhone. Download the software needed and follow the tutorial that comes with it. You should be able to unlock it and use any simcard you like.

If your phone is infact unlocked, and still displays that message, go into Installer in your phone, and install iWorld. Then select the country that the simcard is from and your problem should disappear.
