So I was having the death grip antenna issue like everyone else and then I got a bumper and it didn't really help at all. So when there was the article on Gizmodo about free cases and all you needed to do was pay the shipping and handling I thought OK I might as well spend the 4 dollars and do it. My case arrived today and while at first I thought it was a flimsy little POS after I put it on my phone and noticed after a few minutes my bars weren't dropping by as much like they usually do in my house. I used to lose all bars with the Apple bumper. This new case I only lose one or two. I think it has something to do with Apples bumpers being plastic where you would hold the phone in the bottom left hand corner... The cases.com case I got through gizmodo is all one piece of rubber. Anyway, just wanted to share this with everyone and say it is worth the try on getting a case that is all rubber.
