Apple iSync Uninstall can remove files associated with the use of iSync Beta software. This includes the main application as well as libraries, frameworks, installation receipts and user-associated files (Preferences, SyncServices data, etc...). Files related to the use of HotSync software within iSync will also be removed.
iSync Uninstall 1.0 will not remove any other personal data files. Address Book, iCal, and Palm Software are left as is.
