I know Apple advise against it, but as an IOS developer I have always put the Betas on my primary phone. I take the view that if I am going to provide feedback on bugs, and properly explore the features that will only happen if I am using it in anger. At the end of the day, what's the worst that can happen, it's only a phone, it's not like it runs my life support system

Worst case, I have never had a problem with going back to a previous release.
