But the update did not complete successfully even though I followed all of the prompts and did not unplug the USB cable during the process. But this process did not go well, as the firmware update was "unsuccessful".
When I tried to restore the phone, I got a message saying "The iphone "iphone" could not be restored due to an unknown error (-1)".
Now itunes cannot restore the phone, even though it will load the drivers and recognise that there is an iphone there, and it recognises that it requires requires a restore. So, it goes through all of the process in attempting to restore the firmware, but with out success.
Its bad timimg on my part cause she really needs a mobile the next few days while in hospital. Any advice greatfully accepted asap.
