Hi all,

I receive the unsecured call warning on most of my calls and shortly afterwards the call cuts off. Is any one else experiencing this problem?

I know this is beta, but is it possible to downgrade back to iOS 4? I have the back-ups.

The two events may be coincidental. The cell in your area you are connecting to is unencrypted - iOS 4 won't make a difference there, you simply won't be told about it.

You may just be experiencing dropped calls for whatever reason. Perhaps the cell in your area is undergoing maintenance and is currently misconfigured. Try it out in a different location.
 
Keep in mind this is a beta; there are plenty of bugs to be worked out. Plus, in the notes accompanying the official beta, Apple states that it is not recommended to use the beta on a personal device, ie: A phone you would make calls on.

Agreed. You can go back to 4.3.3, but you just won't know that you are on a unsecured network. Otherwise nothing really changes
