Apple is still signing for 6.0.1 so you can RESTORE BACK to 6.0.1. Just download the 6.0.1 IPSW for your device and then press the shift key while pressing restore (on windows) which will open a window. Select the downloaded IPSW and you'll be back on 6.0.1. And since Apple is still signing 6.0.1 THIS IS NOT A HACK
OR AN UNAUTHORIZED downgrade. So it DOES NOT void your warranty because Apple is allowing you to downgrade because they've allowed the 6.0.1 window to remain open. I did it for a friend's iPhone and it all worked out fine.
