help uninstall activesync

[faceoff101]

Does anyone have a way to manually delete all the crap left over after using the add and remove to uninstall activesync 4.2? I would like to update to the newer version, i just got my titan today and it told me to update to 4.5, so before i install 4.5 and all the horrid stories i read about the install and conflicts with left overs from previous activesync can some one school me im a fast learner.
