We are on them pretty much all day everyday, and this free smart phone infographic does a deep dive into the interworkings of our favorite little devices. Call log? Check. Recording button? Totally. Media player? Of course. Along with the phone, these images come with nine commonly used icons, from location to a good old shopping cart. Use them however you like!
Remember, the zip file comes with both a .jpeg image and a fully editable .eps image allowing you to customize the image exactly how you see fit. If you need a program to edit the .EPS, try Inkscape.
