Samsung Galaxy Gio network menu I have a problem with my galaxy gio. It has a network lock (I think) and I've tried to unlock it. The problem is that I have the unlock code but the phone doesn't ask for it. It is there a menu or a key code to open that menu to enter the unlock code or any other solution ? 

Thanks
I've solved the problem. The device has a custom rom and you cannot unblock them so. I had to flash the device with a stock one and Odin and then it asked me for network key.
