I recently purchased an iPhone 5c. This was the first iPhone for me. Last night I was doing something on iTunes for my phone (on my PC). This morning, at zero-dark thirty, I picked up my jailbroken ipad2 and noticed that I could not adjust the brightness with my pull-down app, nor could I access Cydia nor any of the apps, like Barrel and such. The first thing that I thought was that iTunes had automatically reset my ipad2, which would have p1$$ed me off. I checked my iOS version and it still showed 5.1.1, which still confused me more. So I powered it down and after it started back up, everything was back to normal. It was still jailbroken. Yea!!! I have never had this happen before, and I have had this iPad jailbroken since the beginning of 2012. Do you think iTunes had anything to do with this? Is there anything I should be doing regularly with my iPad to prevent something like this from happening again? Should I be backing it up to iTunes even if it is jailbroken? Don't want to sound ignorant. Thanks.
