I am extremely excited to get my first iPhone (a 4S) on Friday or Saturday. I have an old 2G iPod touch from a few years ago, and one of the first things I did was to get a good screen protector, since it ends up in my pockets with the keys and everything. I am going to get a case for my new iPhone of course, but I was wondering, which is the best screen protector to get? I'm not sure where to start, I have been out of the loop on this since a few years ago.
