freak out
If it is the latest ipod touch, then you can set up a tracker if you lose it, but I am unsure how.
You will lose every thing that is on it
no at least not when you are updating the ipod touch to the 2.2
no
No it will restore the apps automactically
Be rude and mean to them
I'm not sure...I can't remember
no it does not but if it happens to yours get it checked
If you jailbreak correctly, no, you keep all your songs on your ipod after jailbreaking.
about a month
If you have registered it, they might be able to pay you back, but , otherwise, there's nothing you can do=(
