Crack you iphone?

If you have an iphone 4 or 4s ,you will know how fragile it is when u drop it.Pretty sad right?Thats why apple is planning to put an airbag in the upcoming iphone.It is to prevent it from drops,it something like the airbags you see in your car .LOL,anyway all this are just rumours ,nobody is sure about anything until apple releases its new iphone next year.
