On the device summary page in iTunes 11. Under the option setting is Turn on Wifi Sync.
With your phone conneted by USB if it is already checked I would uncheck it Click Apply
Then when sync has finished check it an resync. When all is done disconnect your iPhone and it should remain in the lefthand sidebar.
If You do not have the sidebar turned on then View > Show Sidebar
