I did this last night, and managed to get it semi working. On boot the phone works totally fine but as soon as I lock it and unlock it - I get a totally non responsive phone for about 4-5 minutes, not even the side buttons work. The only way for me to safely unlock the phone now is by swiping right into the "widget" screen and entering my password that way. Then it's totally fine - Anyone else experienced this/fixed this weird bug?
I also cocked up the facetime camera and speaker for phonecalls but, I'm gonna worry about that in the next comment
