iPhone device timeout error when syncing

A person I know began getting a "Device Timeout Error" when syncing his iPhone with iTunes. All his contacts, photos were being synced but the problem occurred when syncing Music and video. Both iPhone and iTunes were on latest software versions. The problem was fixed after following these simple steps.

Note. For this to work, your iPhone/iPodTouch has to be jailbroken.

I found the original solution from here. The solution is to delete /private/var/mobile/Media/iTunes_Control folder from the iPhone and sync with iTunes. This should work for both iPhone and iPodTouch.

Here are the detailed steps to follow.

1. Download DiskAid or iPhoneBrowser. On Windows you need .Net Framework 2 for this. (I'm using DiskAid)
2. Connect the iPhone to the computer. (close iTunes if it is running)
3. Open DiskAid or iPhoneBrowser. It will show you the folder list of the iPhone.
4. Navigate to the folder /private/var/mobile/Media and delete the "iTunes_Control" folder in there. (be very careful NOT to delete any other things)
5. 
6. Close the application and Sync with iTunes.

I don't know the exact reason for this problem. But that person told he changed the USB port that he plugs the data cable. It may have something to do with changing USB ports or the machine you use to sync.
