I got my iPhone 4 today, and updated it to 4.0.1. I noticed the camera would sometime close its shutter, and wouldn't open it again - even if I closed all the apps on the multitasking-menu(including the camera). It would however work properly if I restarted the phone, which leads me to believe that it's a software-issue.. I've tried restoring the phone to 4.0-firmware, but everytime I try, iTunes just says "3194 Error". I know that downgrading probably won't solve anything, but I might aswell give it a shot... Does anyone know how to make the error go away?
