A friend of mine is willing to put me on his developer list, and I am very tempted. I did some research on stability and downgrade options etc, but I can't really find anything on the updates. If I install OS4 Beta, will I be required to update the beta all the way? Some random guy told me the phone would lock itself down if a I neglected to update to a newer version of the beta. So - what I am asking. Could I hypothetically install OS4 beta and not update it until actual release? Thanks!
