Why is my iPhone 4S taking forever to restore?

So I jail broke my 4s a month ago and now I want to put ios7 on it so I restored it, after backing it up on iCloud. But it still has that black screen and silver progress circle and has been like that for 45 minutes. The circle is still moving, so it's not frozen. Should I be worried?

Try to put your phone in DFU mode for the recovery

Entering DFU Mode (Official Instructions)
Plug your device into your computer.
Turn off the device.
Hold the Power button for 3 seconds
Hold the Home button without releasing the Power button for 10 seconds
Release the Power Button but keep holding the Home button
Keep holding the Home button until you are alerted by iTunes saying that it has detected a device in Recovery Mode
Make sure the device screen is blank and no logos are present

  • Why is my iPhone taking forever to sync? This is all I see when I sync. I just installed iTunes and this is my first time syncing to this computer. I just upgraded to iOS 7 today Also, my iPhone doesn't have the "Syncing please don't remove" like it does on my other computer. Mark, I find your lack of knowledge disturbing. I saw your avatar though and I was surprised. Usually Americans are smart *sarcasm*
