So i'm a new iphone owner and realized with a 2g you can't find anything in retail stores! It's not that old, but apparently best buy only has 3g things! I'm looking for a harder type of case, something as slim as possible would be preferred, I just want some added shock protection. I did some research and found a bunch like Agent 18, Incase, Griffin wave(The one I'm leaning towards). I'd like something without a "huge" logo of the brand on it, and the slickier the better... seems all the best cases are 3g only I'm also searching for a new screen protector, the person I bought the phone from has one on there but its getting some bubbles and I'd like to replace it. Do you like going the expensive invisibleSHIELD type of route is best? (Do they last forever once applied?) or just trying to find a pack of regular ones that you can change out if they start to peel. Thanks in advance!
