Hi Guys. i was using 3GS 4.0.1 jailbroken without any issues. Just two days ago i got my new iPhone 4. I restored it from my backup to 4.0.1 and jailbroke it. It was absolutely fine. But i kept browsing cydia and installing and uninstalling apps and themes. But today i realised some of cydia apps are not working normal. Most annoying is LOCKDOWN PRO. which is so bad that i does not let anything run. I have to start the iPhone in safe mode to uninstall it. After uninstalling lockdown pro evrything was normal. But i really liked Lockdown pro and its working well on my 3GS with 4.0.1. So i thought that i will restore my iPhone 4 again from the backup to unjailbreak. so that i would again jailbreak and reinstall everything as lockdown pro never worked after that. But to my surprise when i restored it from the backup to 4.0.1 using iTunes it was already jailbroken. Is this Normal? i want to restore it to unjailbroken firmware 4.0.1 so that i could jailbreak it in future. Please suggest me something.
