Anything better than Nothing!
Before I got an iPhone, people told me horror stories of big cases turning their pockets inside out, and generally bulking up their cute little toy.
Needless to say, I thought they were crazy.
Then, I fixed this iPhone 4 and got it on line about 6 months ago.
Have to admit I now see their point.
If you use yours on construction sites, or hunting & fishing, by all means spend the $40 for the top Otterrbox.
A buddy has one on his (larger) Android phone, and hands it to his little kids when he gets home.
Someone here on the forum so elequoently called the iPhones, a "slippery glass brick".
I couldn't agree more. Never leave home without *some* sort of case!
Ive seen 4's with chips along the edges oh their screens.
(the metal frame doesn't show much wear)
On iPhone 5, the paint easily chips, and wear shows quickly.
If you don't go for the Otterbox, at least put on a TPU or bumper.
Both available on Amazon under $2 shipped!
Screen protectors are 2 or 3 for a dollar (shipped).
And for bumper users, clear back protectors are just as cheap.
So, for $5 or $6, you can try both and decide if you need more.
In either case, they won't slip out of your hand.
Both keep the screen off the table if laid face down.
(same can't be said of many "clip-on" cases)
