The information tab has disappeared in the latest version of itunes but only Mavericks, it no longer allows local synchronization, only through iCloud
quote
Note: These instructions are only if you are using OS X v.10.8.5 or earlier. If you use OS X v.10.9 or later Mavericks, contacts, calendars, and other information will be updated on their computers and iOS devices via iCloud. For more information, see Help iCloud at icloud.com.
I do not know what will be for the reasons that have made this decision, because they left out all those versions of iOS devices where you can not sync with iCloud, and of course those who do not want to use iCloud to sync contacts, calendars .. .
greetings :)
