Nova Media has released iHub, a new tool for automatically syncing contacts and calendars between the Mac and multiple mobile devices such as the iPhone, iPad, and iPod touch. The software is capable of sharing information wirelessly, and supports both Wi-Fi and Ethernet connections. It can be used to share existing address book groups, and can instantly sync any changes as long as an internet connection is available. Users can also make changes while offline, which will automatically sync once a connection is re-established.
