I've downloaded the correct IPSW file for the iPhone 4 using BitTorrent.
I cannot use the Apple servers because the connection keeps dropping and the download does not resume where it left off.
The iPhone can download the file itself, but again unreliable connection prevents me from doing that.
I want to move the IPSW file to the iPhone using iFile and then tell the iPhone to update from the IPSW file on the iPhone.
Where do I place the IPSW file on the iPhone, so that it will see the file and perform the update?
And are there other files I need to update so that the iPhone will see the file.
