I just purchased an iPhone 4 on a 24 month contract on monday, it all seemed to be working fine up until today. So I decided to jailbreak my iPhone, the jailbreak worked fine and the phone started up as usual, so I went on Cydia and downloaded a theme, but afterwards it asked to reboot the device, so I did. But it didn't reboot, it just stayed on the Apple logo screen for a very long time and wouldn't restart. So I decided to try and restore my phone, so I put it in recovery mode and plugged it into iTunes, but now, iTunes is saying: "iPhone" could not be restored. An unkown error occurred (1013)" Any help would be appreciated. Oh just in case it helps, I'm running it on Windows 7, just updated my iTunes too.
