The other day I saw a lady who had the Agent 18 Eco Shield for her iPhone and she had some sort of screen protector on her iPhone. She said she bought it at the Apple store but I'm not sure what it is. I've searched the online Apple store and haven't found any. Hers had an almost "rough" surface. I use the term "rough" in quotes because it isn't rough but that's the only word that I know that describes it best. Either way, her screen protector was very nice and you couldn't even tell it was there unless you were using the iPhone and it was very nice. Does anybody have any idea what this could be or where I could find it (online Apple store, perhaps?). The nearest Apple store is a few hours away so it's not like I can just run down there to see if they have it. She did say that she spent maybe around $6.00 for it, if that helps any. Thanks.
