I have a Droid 4, version 4.0.4, system version 6.16.217.XT894. This morning there was an system update, which I did and it took 15-20 minutes. Now the whole look of the phone has changed (which I'm not thrilled about), and I keep getting a message that says there is a security update required on my Email account. If I do this it's going to erase all my data and do all kinds of other things I don't want it to do, but I can't make the message go away. I don't know much about these phones other than I've figured out how to use them. What is going on?????
