Are the owners of this case certain that you can't squeeze your iphone in if it has clear side wraps so as to protect the band in the case of any dust etc finding its way in?
You could get away with a back screen protector but not the sides. The case is really tight as it is.
I had a 4S with the side protectors "stickers" from Lucky Labs and the PS Air Jacket case i had for it cracked on one corner because the case had such a tight tolerance.
