I currently have an iPhone 4 firmware 4.3.3 that is jailbroken. I'm having issues trying to upgrade to the new iOS 5.0 firmware. iTunes keeps giving me an error. Now that iOS 5.0.1 is out i really don't want to upgrade to that firmware because it has not been jailbroken yet and I don't think I can go back to stock after having it jailbroken. Is there a way to get some of the features iOS 5.0 has without upgrading? I was hoping to get the new safari features as well as the new notification center. Any ideas??? Thanks in advance for any replies...
