Ladies and gents. My girl has an iPhone 4 and needs a new case for it. I was gonna get it for her for Xmas. Ideally, she's want something slim and that has some silicone on it to prevent it from sliding everywhere. She has a silicone case on it now that she has stretched out from fidgeting with it all the time. I've searched Girly iphone cases, but the threads were minimum and old. Can you guys suggest any cases for my chick?
