Put your iPhone it in the right case and it can survive a drop from 3,000 feet in the air. But wouldn't you know it, phone cases aren't only just for protecting your phone, they have other great uses, too.
There's the PocketPlug for iPhone 5 and 5s that plugs into the wall and charges your phone, this handy wallet case, or, you could pick up the yellowjacket case meant for self-defense, or get a workout with this odd dumbbell case. There are so many different options!
Now, there's a new case out that claims to double your smartphone's signal strength. It would make for better coverage and faster downloads. It could even improve your battery life! Could this really work?
