Not that this helps, but out of curiousity what model did you get?
What solution did you get it for?
But to try and be helpful..
1. We had one a while ago just to let the docs search safely, and I set up a dummy Google account to use. It wasn't attached to anyone's personal Google stuff.
2. That's strange, usually the home page always sticks when I change it under settings. The Guest mode might not save anything though.
