I've tried to update my iphone 3Gs to the IOS 4.02 and now it's frozen on the itunes logo with the USB lead symobol. Tried restore but screen remains frozen!
did you take these steps
Yes I'm afraid I have tried all recommended measures to no avail.
Apple no longer signs iOS 4.02. It's not possible to (legitimately) install it.
What exactly are you trying to do?
Have been trying to restore previous settings which I have now managed to do.
Thank you very much for your attempt at assistance.
