I have an iPad1 which is on iOS 5.1. I used to have it jailbroken but removed it a while back when I installed iOS5, and today I was bored so thought I would jailbreak. It seems to have worked just fine, I now have cydia installed, but nearly all my original apps have been deleted. I guess I can go back to iTunes and sync them back on, but it's a bit of a worry, I'm now wondering what else has gone? If I restore from the backup I took just before the jailbreak, will that remove the jailbreak?
