ISync

iSync was developed by Apple to allow users to data across multiple computers, PDAs, cell phones and iPods. Data that could be synchronized included contacts from Address Book, dates from iCal and bookmarks from Safari.

Online use of iSync required an .Mac account and its features were integrated into the Sync tab of the .Mac preferences pane in Mac OS X 10.4. The System Preferences pane had the ability to also sync keychains, Mail accounts and Mail rules, signatures and Smart Mailboxes. iSync was still used in Mac OS X 10.4 to add devices such as Palms and cell phones. Beginning with iTunes 4.8, iSync no longer synchronized iPods; these settings had migrated over to iTunes.

The final version, 3.0, was supported by Mac OS X 10.5 (Leopard).
