yifanlu, I just confused with the following statement.
1. That means I need to have Kindle 3 and 2, right?
2. How to uninstall or undo this thing on Kindle 2 (including remove the backup recovery package)? Because I afraid that if I feel doesn't like software v3.1 for what ever reason, I can't revert back my K2 to the original state.
3. After the upgrade K2 to run v3.1 software, what will happen if Amazon release an update of K3 software?
