Free wireless mobile synchronization service NuevaSync has updated with full support for multiple Google calendars, including sync for read-only holiday or shared calendars, making it a fairly powerful business program.

NuevaSync gives you over-the-air synchronization using your mobile device’s built-in support for Microsoft Exchange, and acts as a pass-through gateway to your Google Calendars and Gmail contacts with support for updating directly from the device. The new updates also give you separate colors per calendar, and you can choose which calendars you don’t want to synchronize. Sounds very flexible and powerful indeed.

The new updates definitely make it worth a look. NeuvaSync is a free service, and works on any phone with Exchange support, including iPhone/iPod Touch. Web site is here: https://www.nuevasync.com/

It’s safe to say that the iPhone isn’t just a “kid’s toy” anymore.
