So I already have a case for my iphone 4s, but am curious if there is anything I need to look out for in regards to just getting a clear screen protector for the face of my screen? Are some screens worse than others? I assume most are the same. Just don't want scratches, etc. Also, do they have any affect on the touch screen capabilities of the iphone? I know they will all work, just curious if thickness or material matters.
Thanks
