There are a lot of iPhone 4 covers out there, but the iBoobies may just take the title of "most titillating phone cover ever."
Shaped like a pair of breasts, the iBoobies case is the latest in a long line of novel cellphone-protecting designs. The manufacturers describe the anatomical case as "soft and squishable," and indicate that it "serves as both a phone case and stand." Simply place your iPhone on its back and the bustling bosoms will prop up your cellular device for easy viewing and manipulation. How you're supposed to fit this into your back pocket, however, is something you'll have to figure out.
If you're not a fan of boobs, there's always the Booty Call iPhone holder (also pictured in this gallery).
