Im having problems. I decided to install it just for fun but thought it was causing some problems for me so I uninstalled it. Now, when I look at firmware version, it says "N/A." It also says this in iTunes. I also cant change bluetooth settings. It says "bluetooth not available." I have restarted and reinstalled / uninstalled it so many times, but no luck. How can I fix this? Now itunes is looping an error saying my computer is not authorized. Awesome... Also my status bar clock likes to disappear when I reboot. WTF?
