Next Apple's R&D is gonna start thinking about developing the iSmoke, they sell a package with some dry wood, a box of matches and 1 blanket.
Instructions: take wood out of the package, place it on the ground, light a match and set the wood on fire, wait 2 to 5 minutes to gain optimum network coverage, then use the blanket to comunicate via smoke signals!!
Then Apple's R&D remembers that they advertized about how this system would have a exlent network coverage, but they forgot about windy days, and since on windy days you can't archive the necessary smoke consistency to comunicate they will get sued for 5 million in damages from false advertizing...
