I think it's pretty much a habit of everyone's to play with their mobile phone. The only problem is when you're happily flipping it through your fingers it is likely to fall to the ground and smash. The Yo Yo cellphone, on the other hand, encourages you to play with it. Heck it encourages you to whip it around and toss it up in the air.
Created from the crafty mind of Emmanuel Hanson, the Yo Yo cell phone also comes complete with a charger so you don't have to worry about your handheld losing juice while you play 'walk the dog' with it.
