I am using the 800mhz F104 kernal, as well as JStop, Preset Reset daily and that other 'fix' to speed up the Pre (only send logs minimally)

What I would like though is an app that periodically (weekly) clears all the phone, web, google maps history, as its known to slow down the Pre.

Does an app like this exist?

It would sort of be like the System Cleaner app in Windows.

Please, let me know if this is available.
