Why am I unable to update my iPhone os?
I have found that I am unable to update my iPhone 3GS from 3.1.2 to 3.1.3. When choosing either to download and update or just download, I get the following error:
"There was a problem downloading the software for the iPhone (name of my iPhone). An unknown error occurred (-23)"
The same thing happens when I try to restore the phone (including trying to restore in recovery mode), which scratches that idea.
I have uninstalled iTunes and reinstalled, with no change.
And no, it's not jailbroken.
Is this a good question?
