webtop2sd
It is recommended that you do not modify the WebTop environment in phone's own flash, but instead create a partition on SD card and use webtop2sd utility to copy phone's WebTop. webtop2sd will then mount this partition ontop of the phone's own stuff and if it get's screwed up you'll be able to go back to the blank slate and use your phone's WebTop again.
