Hi, people! I have just bought this case: Vapor Element case.Its made of aluminum. I gotta tell you that I feel comfortable about my iphone's safety now. It has some internal rubs that absorbs the impact if it falls. Anyway, my phone now is a little bit bigger and my concern is: how about the reception? Does any of you have this case? I've used my phone with and without the case and didnt notice any major difference, but I am new at this... its my first iphone (ip4s) and I received it yesterday. Should I buy another case? By the way, any case tips?
