Hey everyone, this video is going to teach you how to restore your iPod or iPhone for whatever problem you might have. How to get the firmware, and how to put all the files back into your iPod or iPhone back into your iPod or iPhone just how they were before you restored your iPod or iPhone. Doing this will erase all cracked apps, and stuff from cydia. This will NOT erase any of the files that you have on iTunes, but it will erase everything on the iPod or iPhone. I will be showing you how to put back all the stuff that’s in your iTunes library at the end of the video.
