Let me start off by saying that I am extremely careful person ninety percent of the time, especially when it comes to the technology I own.
I bought this case as an investment for that other ten percent of the time when I fail to guard my phone with my life.
I've only dropped my phone a handful of times and this case has protected it from what I believe would have likely been a disaster worth of damage to such an expensive and such a precious piece of technology.
The outward-pointed rubber/silicone edges really do protect the phone from any catastrophical amount of damage that the phone might incur in a damaged situation.
I would like to take this opportunity to say thank you to DLO for inventing the Jam Jacket and saving my phone (that is, if you guys are by chance reading this). I also hope you guys make a similar product for the iPhone 4 (which I just bought) with colors other than just black for your customers in America.
So if you want to protect your iPhone, buy this case (it even comes with screen protectors in most location) to protect your precious phone/toy/investment. You will be happy you did.
