The disappearing status bar has to do with 3.0's problem with the info.plist file that is in many themes. Check to see if the theme that you are using has the info.plist file in the theme. If it does, try deleting it (save it somewhere first) then reapply the theme. Let me know if this works for you all as it did for me. I actually then took a info.plist file that worked properly, without the disappearing status bar effect, and plugged that into the other themes. Now, no more problems.
