If you're ever on a particular page and would like to make that page your home page, do the following:
Menu Key > Options > Browser Configuration > scroll to the bottom and highlight "Choose Current" > press the trackball to confirm your choice.

This randomly happens to me and its not that the OP sets it to the agree/disagree site in the browser option page. it randomly does it on its own. I have mine set to google.com and when it sends me to the facebook page, it won't let me set it back to any other page. The only fix I have is a battery pull and even a soft reset won't change it back it definitely sucks!
