Anyone using this current build on your main phone? I'll see how the next few days go using such an early beta (which I don't normally do) on my Lumia 830 phone. If all else fails, I'll pull the sim and put it in my other phone.
I installed on my 822. It won't let me access the settings menu, or use the cell network. It shows that there is no sim installed. How do I roll back to 8.1?
