What is the best iphone screen protectors to keep phone from cracking/shattering?

I'm making the switch to an iphone 5 soon, and I'm wondering what the best type of screen protector is. I'm accident prone, and drop my phone quite often. I'm not interested in an Otterbox or anything that is bulky. Which screen protector will keep my screen from cracking? Also, when it comes to buying a case, what type of material would offer the most extra protection? (gel, silicone, rubber, etc.)

Why don't you try Zagg EXTREME invisibleSHIELD iPhone 5 Screen Protector?

"The precision pre-cut invisibleSHIELD applies directly to your Apple iPhone 5, providing the best, most durable protection you will find. This screen protector has its origins in the military, where it was used to protect high-speed helicopter blades from dust, dirt and debris."

Screen protectors do not really keep the screen from cracking.upon release, I believe Zagg will be one of the only options. Zagg original is more sticky and is more likely to peel around the edges over time. HD, is a little clearer but, the material has kind of a memory effect, like if you scratch it with your nail, the scratch may be their for a long while, if not permanently, even placing the HD protector down flat on a table, when you pick it up it will have the tables texture in it for a few hours! Over all I prefer the original even if it is more textured. I have not seen the new extreme one yet.

  • What are the best screen protectors for the iphone 4S? I just purchased my first iphone the other day and have been afraid to bring it out with me or even use it a lot until I get a screen protector and case. I looked on Amazon and there are so many different brands and styles. I also did some research, but I still don't know which one is the best. I want a good screen protector that doesn't cost too much. Which brands do you suggest? Also, do they sell cases with screen protectors in one or are they sold separately.
