After getting the 4S and then seeing some drop tests, I decided that I need a case. Here's one question: Do you guys think it also needs a screen protector? Personally when I had my iphone 3G I hated plastic or vinyl screen protectors. I was looking at the ivySkin Wrangler case, as the analogue one for the 3G was actually pretty good. I actually liked the glass protector compared to what else was out there. But is it really necessary? the 3G was easily scratched and it seems that the iphone 4 and 4S have much more scratch resistant screens. That takes me to the second issue of scratching the body and shock resistance. TIA, Really hoping you can help me out!
