It sounds like your usb port is damaged. Look in the port and see if there is any visible damage. Also, check the usb cord for the iphone and see if it is damaged.



Please take time to rate.

First, calm down, grab a cola and chill for a second.
Ok, most likely you have down what I have down and unplugged the iPhone before all the jailbroken data was downloaded and setup.
Follow these steps, yes they work I've had to do this twice now.

NOTE: You need to be plugged up to your computer for this to work

1. Hold down the POWER and HOME buttons untils your phone reboots.

2. Hold POWER button until the iPhone powers OFF

3. Hold POWER and HOME buttons, iPhone will now power on.

4. When you see the apple logo, release the POWER button but keep holding the home button.

5. iTunes should alert you now saying that it has found an iPhone in recovery mode, proceed to recover as normal now.

Also the iPhone screen may go white after doing this until restored, this is normal, it's not broken.

Make sure you've got the latest version of Itunes installed, if you have Itunes on your PC at all.

Try changing your drive letters: Click Start, click Control Panel, and then click Performance and Maintenance. Make sure you are in Category View. Click Administrative Tools, double-click Computer Management, and then click Disk Management in the left pane. Right-click the drive, the partition and then click Change Drive Letter and Paths. Click Change. Click Assign the following drive letter if it is not already selected, click the drive letter that you want to use, and then click OK. Click Yes when you are prompted to confirm the drive letter change.

Try the IPhone now.

MUCH BETTER SOLUTION:
1. Sometimes iphone connection software( espescially on the camera roll) can be confused with software from other drivers such as webcam drivers. LOGITECH ESPESCIALLY
2. If you do have logitech installed or any other webcam then uninstall all software from this.
3. To do this : Go to start, control panel, add/remove programs and select the logitech or any other software affiliated with the webcam . Uninstall it and then restart your computer.
4. Your problem should now be fixed.

p.s. I had been trying for ages until i found this simple solution which worked instantly.
