IDC is out with a new forecast that says smartphone shipments will grow 33% this year. Mobile data traffic, meanwhile, is expected to expand 72% in 2013 after jumping 69% in 2012, reports ABI Research. All signs point to massive growth in the device sector.

How to play it? Apple is a natural choice. But Fool contributor Tim Beyers has three other investment opportunities that may be as good or better, including Google (NASDAQ:GOOGL). Android's fight for supremacy is a sideline to the search king's mobile data collection efforts, which are informed by not only its operating systems and native devices but also apps that exist on other platforms, Tim says.

There's a lot of data to capture. More than 23,000 petabytes overall, ABI Research says. A lot of that will flow through Google's servers, helping the search engine and ad delivery mechanism get smarter and earn more.

But Google also isn't the only opportunity, Tim says. Watch the video to see his other two picks and then leave a comment to let us know what you consider to be the best investment opportunities of the smartphone boom.
