Okay so I'm posting this off my 5 day old iPhone 3GS. 1. I have to Charge my phone everynight is this normal? It usualy has around 30-40 percent battery left when I go to charge it every night. And 2. Can a case effect my wifi signal? I have a White silicone case on the phone that covers it complety but obviouly leaving gaps for the camera earpierce etc. I find that my wifi signal isn't great with the case on. Thanks
