Invest in a protective case! Phones get dropped and easily damaged. I have the Otterbox Defender case and love it! It is a little bulky, but it keeps my phone safe.
Highly recommend the Otterbox Defender.
Funny story happened to me on Tuesday. Went to pick up my fiancé Tuesday afternoon. Got out of the car to get into the passenger seat, and decided I wanted to put my sweater back on. Put my sweater on, got back into the car, we went on our merry way.
As were driving, I cant find my phone. I usually lose it in my purse. Get through the next major intersection, still cant find my phone. Ben pings my phone with the Find my iPhone app, and he looks at me and says, this says its at the intersection of X and Y which is near where I had picked him up. (usually its in my pocket or purse-these dumb pants didnt have pockets. Must have put it on the roof when I got out-had just gotten off the phone with my mom. I have since dropped these pants off at Goodwill)
Oh dear. After going back to where we started, and walking around, we did indeed find my phone on the shoulder of the street. I figured it was about where we changed lanes, probably going around 45-50 mph.
Otterbox Defender was a bit beat up, but my phone is in perfect condition. I decided to replace the case with another onetook the carseat approach with it. It did its job in protecting in the accident, but the one impact was probably enough. Replaced it with another one. Does add a bit of bulk, but totally saved my butt here. And a few $$$. Until I make another bonehead mistake.
So, I guess my recommendations are both Otterbox Defender, and the find my iphone app!
