Jennifer Garner, pregnant with baby #3, is making sure she's up to speed with her gadgets.

Ben Affleck's wifey hit up the Apple store in Santa Monica for a two-hour class on how to use her iPhone. Now that's dedication!

By the look on her face, seems like Jen is giving the Mac guy an I'm-not-sure-I-can-do-this face. Gotta love technology!
