Fits my iPhone 4S with some room to spare.  So if you have a slim bumper or something on your phone it should still fit.  The price is right on for this item.  So far after two weeks no complaints.  I will update this in 6 months or so...as I'm not sure the clip will hold up...but I have had no problem so far.  However, for the cost, I would buy two of these, just in case one breaks.  It was exactly what I needed and provides the protection I needed for the phone.  Thanks again Amazon!
