Hi all, I updated to Beta 2 but the signal issues I had with Beta 1 are still there and they've also removed 4G from the settings! I find that if my iPhone loses signal then it struggles to reconnect and I end up having to reset the iPhone. I've also noticed that it decides to turn itself off and won't turn back on unless I do a reset (holding down the home and power button). This morning my alarm didn't go off and I was late to work because of this! haha. Overall, I've find both Beta's to be really quite bad. I've tried to downgrade to iOS 7 but when I go through the steps iTunes tells me that I can't do it!
