If it isn’t military grade it is probably not going to be able to withstand any and all drops your iPhone 4 may take. This case by Jon Eicher is definitely going to be the toughest case you have ever owned. There is one very big issue with this case though, and that is that this case is one-of-a-kind. The price may not seem like something that makes this case very special since it is only $99, but there are some rumors going around that this military grade case will be available for custom order, if you can get a hold of Jon Eicher. I personally feel that the design is lacking in the overall of this case and that it seems to be something that is not very pocket friendly.
