I have an iPhone 4 (GSM) running 5.0.1 jailbroken with redsn0w and it takes too long to back up. It takes like 4 hours to back up and then when I want to restore my iPhone it says the back up is corrupt and cannot be restored with that back up. So I deleted every single thing (apps, photos and videos) other than my music because its gonna take too long to download all that again. So my back ups were working fine until I threw like 3 movies onto iTunes. I can't exactly remember what happened but I closed iTunes when it was about to back up. And please don't tell me that it is because of my iPhone being jailbroken because I have tried it jailbroken and non-jailbroken on both 4.3.3 and 5.0.1. So I am really sick of this because I cannot back up my iPhone at all! Please is their a solution?
