Since my iPhone 4 should be arriving in a couple of weeks I've been looking at some cases. I still have a trauma from when I scratched my iPod Touch so I definitely do not want to scratch a phone which is this expensive. Still I just can not decide on what case to buy. Since I don't want any hard shell cases I've narrowed it down to 2 cases. This Sena UltraSlim "pouch" and the ZAGG invisibleSHIELD. The Sena case seems nice, easy and even stylish but I'm a bit afraid I will still get some scratches on my screen because you have to constantly get it out of / put it in the pouch. The invisibleSHIELD on the other hand would be pretty much invisible (duh) and offer a great protection at the same time. I've been watching some videos and it's quite a hassle to get it right. And since I'm probably not that handy I'm a bit afraid I will mess it up. But still, I would be 100 % certain my screen does not get scratched at all. Please give me some advice and share your experiences!
