You don't need to do
any of what the OP mentioned, which is a lot of jumping around.
- Just installed SKTools and go to the Today Plugins section
- Unpin and uncheck "Dial Lookup"
So why don't we all do this?
Simple, it disables like all of the Palm hacks for the today screen
This is why HideLogo was invented as it kept the plugin (but hidden) and the Palm hacks.
