This is an actual product for sale called the iBackFlip Hitch. Basically there's a magnetic frame on the border of the back of the iPhone. I think in some cases, the magnet is built into an iPhone case. The magnet is powerful enough for you to post your iPhone on a metallic surface like a fridge or wall.How does it hold to the back of the iPhone? Unlike the iPad, there's no magnets to hold it... You have to glue it on? That's just dumb.
